What's your running shoe's medical history?

 

Today's run (treadmill): 25 minutes

When you go to a medical office for the first time, they usually present you with a clipboard loaded with forms that you have to fill out before you can see the doctor. Among those forms is a checklist for your family medical history. It makes sense since the best way to predict future health problems is to know your areas of risk. I'm applying the same concept in assessing the useful life of my main pair of running shoes.

I've always been skeptical about the commonly-held view that trainers should be replaced between 300 and 500 miles. Just as people may carry greater risk for certain illnesses, some shoes and brands seem predisposed to wear out sooner than others. My first pair of running shoes were some Nike Foot Locker specials that only lasted about 400 miles. But I ran in a pair of Brooks Adrenalines for 700 miles before I retired them.

People tell me that they notice when their mid-soles have worn out after a few months. I think it's all in their head. Unless you are a large person, it's unlikely that you would significantly compress EVA enough to matter. I've come to believe that it's the out-sole that determines the life of a shoe. When I've needed to replace a pair, it's usually because the wear pattern on the bottom has caused a change in my foot strike.

Of all the running shoes I've owned, the pair I've liked the most were the original Saucony Kinvaras. Unfortunately I loved them past the point where their out-sole could provide me a stable platform and I ended up with a knee problem. After 466 miles, I took them out of the rotation. I'm currently running in the Kinvara 3's, a great shoe as well, but I've reached 436 miles with them. That's only 30 miles less than what I got out of the first Kinvaras.

Saucony's new Virrata looks interesting

So far, I've experienced no knee issues when running in the 3's, but the wear patterns are starting to show. Should I be proactive and replace the 3's in case they go from good to bad in the next 30 miles? Or should I put faith in the idea that Saucony may have engineered a more robust out-sole in the two generations since the first Kinvara? I'm on the fence about it, but it doesn't take much to get me back into shoe-buying mode.

Back to the Spiras, for now

Good buzz for the Stinger

Today's run (treadmill): 25 minutes

Another rainy morning has put me (once again) on the treadmill. I was fine with that. In fact I almost prefer the treadmill when I have limited time and want to have an easy workout. Running slowly outdoors means that I need to take more time to complete the loop back to my house. That results in less recovery and transition time before I start my workday. Advantage treadmill.

I'm due to post my reviews of the new Saucony Kinvara 3 and the Spira Stinger XLT running shoes on Runner's Tech Review shortly. I'd spent a few weeks running primarily in the Spiras while I waited for the Kinvaras to arrive, and then switched to running mostly in the Saucony's over the past few weeks. In between, I ran in the Saucony Hattori's for a 5K and for some treadmill workouts. This morning I went back to the Spiras so they'd be fresh on my mind when I start my writeup this weekend.

Although I do focus on running shows more than the average mid-pack runner, I no longer think that a shoe will make a measurable difference in my performance. More specifically, I don't think two shoes within the same genre (race, trail, etc.) will provide significant differences. It comes down to whether a shoe feels right, moves well and enables my best performance. The Spiras continue to impress and it's interesting to see how they'll compare to a Tier 1 player like the Kinvara 3.

Kinvara 3, Spira Stinger faceoff

Kinvara 3's - a worthy successor to the original

Spira Stinger XLT's - light, fast and comfortable

With less than six days until the LI Half Marathon, I'm still undecided about which shoes to use for the race. Six months ago I wouldn't have hesitated to go with my Hattori's, but I haven't run with them much over the last two months. I'm not sure how those flat, non-cushioned shoes would feel after 13.1 hard miles, especially with my recent issues with mid-foot pain.

It has really come down to two shoes to wear - the Saucony Kinvara 3 and the Spira Stinger XLT. The Kinvara 3 is a minimal running shoe that I'd anticipated for a year, only to be initially disappointed when I finally ran in them. My issues, it turned out, were not with the shoes, but with the foot inside. An acute pain along my left mid-foot was actually a slight injury that has since healed.

The other candidate shoe, from Spira, has been a delightful surprise. I agreed to evaluate this model on Runner's Tech Review, thinking they were the type of gimmicky running shoes I often lampoon. It turns out that the Spiras are one of the most comfortable and runnable lightweight shoes I've ever encountered. As far as their promise of slicing 15 seconds per mile off my pace, I'm not so sure I'm seeing that benefit. But the Stingers have carried me well over many 8+ mile runs.

I wore both pairs on my runs this past weekend and I'm definitely leaning toward the Kinvaras. While the Spiras have their energetic "Waveform" technology, the Kinvara 3's feel like my original Kinvaras, the highest compliment I can give to a running shoe. Saturday's 12 miler was grueling, but my feet felt great. The light weight and low platform of the Kinvara 3's have almost convinced me to go that way. Almost.

First run: Saucony Kinvara 3's - a great update to a favorite shoe

Today's run (street): 4.5 miles

After yesterday's long run, I was prepared for an easy workout this morning. I'd wanted to try the new Kinvara 3's for the first time on the treadmill, but the machine is currently down, waiting for parts. Plan B was to run outside, but the weather report wasn't encouraging. I determined that an early run would allow me to dodge the rain that was predicted to fall by mid-morning.

The temperature was 49 degrees when I hit the road in the new Sauconys  at 7:30 AM. The fit was superb and these shoes reminded me of the feel of the original Kinvaras. I've been having trouble with soreness at the bottom of my feet as a result of stepping up my long runs in recent weeks. This is not plantar fasciitis, just old fashioned pavement-pounding swelling.

Compared to the Spiras, the Kinvara 3's feel more agile. I suppose this has to do with the lower platform and flatter (4mm) drop. Like the Kinvara 1's, the 3's move well with the foot, and they do help facilitate a mid-foot landing. The Kinvaras felt so good that I changed my run plan from slow and easy, to comfortably peppy.

I fully enjoyed the run, following a different route than usual, and appreciating the cool, cloudy conditions. At one point I crossed paths with another runner and ran behind him for a few minutes. I was concerned that I would overtake him at his current pace. I didn't want him to feel uncomfortable, so I ducked into a side road that looped back around and opened up more room behind him. 

I finished the run feeling pretty good considering the distance I'd covered on Saturday. The Kinvaras performed well and it's going to be interesting to compare them to the Spiras in the coming weeks. Still, my feet were feeling mighty sore, so I indulged in a foot soak using my wife's foot spa unit. This device provides inferred heat, water jets and vibration. I added Dr. Bronner's Magic Castile Peppermint soap to the water, and it has kept my feet feeling great, long after my soak was over.

I'm pleased to have covered over 13 miles this weekend. I'm hoping that the weather will clear by Tuesday morning when I go out once again. I'm expecting the treadmill to be operational by the end of the week. Fingers crossed for good conditions until then.

My mystery running shoes have arrived

Fresh out of the box

A long day and late night on Thursday translated into another ad hoc rest day this morning. I had the best of intentions but, after getting less than 4 hours sleep, I felt I needed more rest. I intended to elliptical but the advantages of skipping that workout outweighed the disadvantages. It's been a pretty poor week for running, but with this week's schedule, I knew I'd miss a few days.

On the plus side, my mystery shoes arrived last night. I was too tired to even try them on when I got home but I will tonight. They're the new Kinvara 3's that I've been anticipating for a very long time. I loved the original Kinvaras but didn't really like the 2's. I'm hoping the third time's the charm. My one minute assessment is that the K3 seems to be built more like the Mirage than the original Kinvara model. That may be okay. I went up 1/2 size and hopefully that will provide enough room in the toe-box to make for a perfect fit.

Speed takes effort, it's that simple

Today's run (street): 2.5 miles

The UPS truck mocked me as I drove into my driveway last night. The UPS driver usually does his deliveries in my neighborhood around the same time that I get home from work. I watched as he carried what looked like a shoebox-sized container, but he dropped it at a neighbor's house. Saucony is supposedly looking into what's happened to my pre-launch Kinvara 3's. I'm thinking I may never get them.

As much as I've anticipated the Saucony's, I'm still appreciating the Spira Stinger XLT's. I skipped yesterday's run, but went out this morning. Again I found the XLT's to be comfortable and responsive. I moved well during my run and, while my PE was relatively low, I felt like my pace was brisk. When I came to the end of my run I looked at my Garmin, only to see that I'd covered my route more than a minute slower than expected. So much for getting that bonus 15 seconds per mile from the XLT's.

I think the lesson I reinforced today is that, at my level, speed should feel hard. If I don't push it, I shouldn't expect to put up good numbers. Due to some scheduling issues this week, I'm swapping my Thursday elliptical session with a run tomorrow morning. I'll put in more effort and see whether that makes a difference. Perhaps the 15 second bonus only happens on harder runs.

Saucony's secret news is leaking out!

Today's run (treadmill): 25 minutes

The cat seems to be out of the bag in terms of the "top secret" news that Saucony plans to share. Via re-tweets on Saucony's Twitter feed and through blogs I follow, it seems like the running shoe stork is dropping off boxes of the pre-market Kinvara 3 to bloggers and reviewers like me. This is a shoe I've been anxiously anticipating.

After reading people's first impressions, I'm even more excited to receive my pair. I'm also worried that something got botched up and my shoes won't ever reach me. In the meantime, I continue to appreciate the feel and responsiveness of my new Spira Stinger XLT's that I wore on today's run. It was my third workout with the XLT's and the second on the treadmill (raining this morning). I hope to take them out on a long base run tomorrow.

So as I wait for the Kinvaras to arrive, I'll be happy to run with the XLT's. I'm really curious to see if the Wavespring technology delivers any extra support when I face that last big hill at the end of mile 8.

Looking for my winter running shoe

Perhaps I need some (new) balance in my running

After trying on the Kinvara 2's only to realize it wasn't the shoe for me, I'm back to rethinking my winter footwear. I really loved my original Kinvaras. In fact, I'd still be running in them except that I wore out the Kinvara's mid-sole to the point where I began experiencing knee pain. That breakdown coincided with the timing of my half marathon that I ran while injured.

Green Silence - an opportunity lost

A couple of years ago I anticipated Brook's launch of the Green Silence, their first "minimal" shoe not made specifically for racing. I couldn't wait for them to go on sale. I ended up being dissuaded by the salesperson at Jackrabbit who steered me toward the Brooks GTS 10's, a great shoe but it rides too high. I ended up switching to the Saucony Kinvaras midway through 2010.





The Hattori - great except on really cold days



The Mirage - a really good shoe but the fit is narrow



Earlier this year I tested the Saucony Mirage, a Kinvara-like shoe with some stability features. It's a great shoe and I've put in a few hundred miles in them, but the toe width is a bit narrow. I was hoping that Brook's new Pure Project line would provide a shoe that met my needs. I tried on the Pure Connect and really disliked the fit that was narrow and very tight in the arch. The other models weren't much better so I decided to look elsewhere.

After looking at many reviews, I am thinking that the New Balance Minimus MR00 may be a "good fit" for me. My hope was to find a minimal, zero-drop, road shoe that will give me a little more insulation that the Hattori's for winter running. Given that the MR00's aren't due in stores until March, I may need to get through most of winter in the Mirages on cold days and the Hattori's on more moderate days and races.

A return to the Hattori's

Today's run (street): 2.5 miles

Super minimalist ninja

Hattori Hanzō was a famous ninja and samurai who lived in 16th century Japan. I'm guessing that his sword skills were the inspiration behind Saucony's Hattori super minimalist running shoes. I've put about 250 miles on mine since I've got them and I've come to love their purposeful simplicity.

For the last three weeks I've been running in either my Saucony Mirages or Brooks GTS-10's in an attempt to clear up a minor pain I've had near my right Achilles. I figured that the greater cushioning and stability control on these shoes (compared to the Hattori's) would help my healing. It  must not be the shoes because the pain remains, although it always goes away after a few minutes of running.

Since Sunday is race day, I thought I'd end my taper with a run in the Hattori's. It's a different experience going back to a shoe 1/3 the weight of the Brooks. I worried that my layoff from these shoes would cause me some calf pain when I returned to them, but I had no problems today. I ran okay but I'm nowhere near my late September peak. I think the Hattori's provided some benefit over the heavier shoes this morning since I ran 30 seconds per mile faster than yesterday. However, that pace was still far off my target for the 10K. I guess I should reset my expectations for this race and defer my focus on performance until the following weekend when I run the Long Beach Turkey Trot.

Hurtin' Hattori's

Along with the damage to my Hattori's toe box yesterday, that probably came as a result of so much downhill running during the race, I also managed to aggravate my right Achilles to the point of great discomfort. This injury has been a long time coming. I started to notice some pain at the back of that foot (just above the heel) some weeks ago, but it never became worse than an uncomfortable distraction. It wasn't too bad after the race yesterday, but later in the day I felt some sharp pains as I walked around.

I don't know why this problem developed. If it is the Hattori's, I'd think the injury would have happened on both Achilles tendons. But running related injuries never seem to occur symmetrically. It could be a combination of the shoe and the way I run. I've been icing the area and taking Aleve since last night, and that combination has helped a lot.

I considered doing an easy run today, just to get outside, but I decided that might do more harm than good. A slow, easy recovery run wouldn't help my conditioning and it would definitely put more strain on the Achilles. I'm probably going to do most of my running in the Mirages over the next two weeks to see if that helps the problem. I love the Hattori's but they may be getting to the end of their usefulness. I have another pair of Hattori's that I can start to use once my Achilles feels better. When I do, I'll know to replace them soon after I reach 200 miles.

I've found my minimalism threshold

Dare I say "a little too minimal"?

It wouldn't meet the definition of a "Two-a-day" but I did get out late in the afternoon on Sunday for a bike ride. My wife and daughter had gone over to the middle school to play tennis and I thought I'd surprise them with a visit. After I saw them I did a ride around the neighborhood and followed a route that I commonly run. Once again I was amazed how quickly I covered the roads on my bike compared to when I run them. It's also a lot easier to ride these roads, especially the hills, but there's something about the simplicity of running that I far prefer. Must be this minimalist mindset I've adopted.

Regarding minimalism, I made my second attempt to run in the Invisible Shoes huaraches yesterday and it didn't go well. I tried the sandals with socks (much to wife's horror) but kept in the backyard to prevent her any further embarrassment. I'd hoped the socks would protect my toes from the lace but it actually exacerbated the discomfort. I shed the socks and tried another run but it was so uncomfortable I had to stop.

I really wanted to reach the point of minimalism where all that existed between my bare foot and the road was a thin layer of rubber. The Hattori's get me very close to that and it feels correct and natural. The huaraches may be a good solution for others, but I know I'd need to invest a lot of time acclimating to the feel of these "shoes." The Hattori's work for me already. I think I'll stick with them.

Saucony Hattori's: read all about it on RTR

New on Runner's Tech Review

Today is the last day of my vacation. It's been very relaxing and I've had lots of fun with my family and done some great runs. I'll be taking another week off in mid-July when we head to Maine and spend some time at Acadia National Park. I can't wait to run on the carriage roads that are adjacent to the ocean and the mountains.

We've posted our latest shoe test on Runner's Tech Review. Me and the Harrier of the Night both provided our perspectives on the Hattori's after a month's use on the road, track, trails and mountains. I'm on the fence whether I'll go for a run or go out on my bike today. I may just enjoy this last day of vacation by skipping my workout. A little more recovery prior to returning to work couldn't hurt.

Even Saucony's website is minimal

Click on picture for larger view

I noticed that Saucony has changed the look of their website to super minimal this week to celebrate the launch of the Hattori. I just looked at a pair at the Super Runner's Shop in NYC. Can't wait to try them on.

Going more minimal

Today's workout (elliptical): 25 minutes

The waiting is the hardest part

I've been waiting excitedly for my Hattori's to arrive from Saucony. I was told to expect them early this week but, so far, nothing. I'm curious to see how I'll run in a shoe that provides little in the way of cushioning and with zero drop-off between heel and toe. I've been running in "minimalist" shoes (Saucony Kinvara and now Mirage) for over a year without a problem. The Hattori represents a whole new level of minimal.

Last summer I experimented with pool shoes, running a couple of miles around my neighborhood to see how it felt. Unlike the shoes I was wearing, my pool shoes gave me no option but to land forward in my stride. The downside was that my feet quickly developed blisters. I suppose socks would have helped that but the pool shoes were far too floppy to seriously consider for distance running. I'm hoping the Hattori's provide the same connection to the road that I got from the pool shoes but will also provide the protection and comfort of a trainer.

The Hattori's will show me how much minimalism I can take

The Saucony Hattori - a most minimal shoe

Today's workout (elliptical) 25 minutes

I'll be posting my review of the Saucony Mirages soon on Runner's Tech Review and I'm excited that I'll soon receive a pair of Hattori super-minimal shoes from Saucony. The Hattori are a zero-drop shoe that weigh an unbelievable 4.4 oz and are being marketed as a trainer -- not just for intervals and racing. My taste in running shoes has changed for good since I switched to the Kinvaras about a year ago. The lower platform and a flatter drop (the Kinvara's is ~5.5 mm) feels right to me, more so than the built-up Brooks Adrenalins that had been my gold standard.

The Mirages have proven to be a worthy addition to my collection and I would probably appreciate their minimal features more had I tried them before the Kinvaras. Going from the Kinvaras to the Mirages is a bit like trading up from a fast but simple sports car to high performance luxury GT. It will be interesting to run in the Hattori's which may be more like riding a trail bike. That actually sounds pretty good.



Champion Activeflex - lightweight, cheap and painful!

Related to minimal shoes, I was at Payless this past weekend because my daughter needed some shoes for an event. I checked out the men's shoes and saw this Kinvara look-alike on sale for $29.99. I tried it on and was surprised by the way it fit. Not too bad. The shoe was lightweight (it really did seem similar to the Saucony) and the foot bed felt springy. I trotted across the floor and that was when I felt the difference, the upper flexed in a way that dug painfully into the top of my foot. I couldn't take them off fast enough. Another example of why we pay for quality brands.

First look: Saucony ProGrid Mirage

I noticed a box sitting on the front steps when I got home last night and was excited to see my review pair of Saucony Mirages had arrived. I brought them inside and opened the package, not really knowing what to expect. The Mirage is Saucony's most minimal stability trainer and a close relation to my beloved Kinvaras.

The shoes, in jet black with bright red mid-soles, were far different from the Kinvara in look and feel. While the Kinvara is a super light shoe with a very minimal upper, the Mirage feels beefier with a more conventional upper and more structure on the medial side for stability. This combination adds weight to the shoe (7.7 oz for Kinvara vs 9.6 oz for the Mirage). Still, this shoe is under 10 oz making it almost 1 oz  lighter than the ASICS DS Trainer 16 that is considered the standard for light stability shoes.

After trying on the Mirage and comparing it to the Kinvara, I noticed a significant difference in the way the Mirage held my foot. The new shoe felt more substantial, less minimal, with gentle upward bend at the front that provided a feel of forward motion and a natural mid-foot fall. I have not run in these shoes so I don't have a sense of them in action but the initial reaction is promising. I'm not going to wear the Mirages on my race on Sunday but I will plan to use them for my half marathon.

A full review of the Mirages will be posted on Runner's Tech Review after I've had a chance to evaluate them. In the meantime, Check Runner's Tech Review next week to see our evaluation of the new Karhu Fast 2_Rides.

Is the Saucony Mirage for real?

Today's run (street): 3.1 miles

My experience with running in a more minimal shoe has been good and I credit the Saucony Kinvaras for that. When I started wearing these shoes I had concerns that a less constructed neutral running shoe would cause me some problems. Before the Kinvaras I had been running in the Brooks Adrenalins as a daily trainer and I didn't expect that to change. As it happened, the Kinvaras caused no issues with their lack of stability features and as a low arch pronator I'm questioning the need for stability control. The need for guidance support may come with runs longer than mine that top out at around 11 miles.

I'm still keenly interested in minimal running shoes so I asked the folks at Saucony whether I could review the new Hattori, a super light, zero drop minimal racer/trainer. There are a limited supply of these shoes for testing so Saucony graciously offered a pair of the new Mirages, the fraternal twin to the Kinvara. The Mirage has some stability features and a little more structured upper. If the fit of the Mirage is close to the Kinvara I will wear the Mirages during my half marathon. It might be a perfect combination for the 13.1 mile distance. I'll document my experience and review it on Runner's Tech Review.

Men's ProGrid Mirage

Quick summary of the Mirage (per Saucony):

• The perfect light trainer for a slight overpronator
• Lightweight with great responsiveness
• Allows the foot to move through the gait cycle unrestricted

Upper:

• Hydrator collar lining
• Memory Foam Heel Pods
• EVA Sockliner
• HRC Strobel Board

Midsole:

• Heel ProGrid LITE
• High Abrasion EVA (EVA+)
• Supportive Arc

Outsole:

• Blown rubber
• XT-900™

Weights:
Men: 8.9 oz
Women: 7.9 oz

I'm not going to comment too much about my run this morning except to say that it was difficult and my performance was terrible. A friend on the running blogsphere (and a person who ran the Dirty Sock 10K in about half the time as me) commented that blood donation can have a real effect on performance for two weeks after the donation. I'll accept that at face value and not dwell on today's workout. I'm hoping for significant improvement tomorrow but I'll settle for a mediocre run.

Negative splits on a chilly morning

Today's run (street): 2.65 miles

All week we've been hearing forecasts calling for warm weather with predictions that temperatures would reach 70º by Friday. I must be missing something because it has been chilly most days this week and this morning was no different. I listened to the weather report and dressed in single layers for today's run. Fortunately I thought to wear running gloves and I was happy to have them. The winds brought the temperature down into the mid 30's and I found myself wishing for an extra shirt.

Saucony Grid Tangent 4

 I wore my Saucony Grid Tangents this morning for a change of pace but my pace didn't change much. My stride felt encumbered for the first mile but I loosened up soon after that. The second half of my run was 6% faster than my first and though my recent paces have not been extraordinary I've been achieving negative splits on almost every run. I'm hoping to get out for 10 miles on one of the days this weekend. Speed will not be my goal but that doesn't mean it won't be on my mind.

What's next after my Kivaras?

Merrell's new Trail Glove

I'm pleased with the way I feel this morning after yesterday's long run. Sunday was a busy day and I spent a lot of  time on my feet. I thought I might experience some second day aches and pains but after a sound sleep I woke up feeling fine. With almost 400 running miles on my Kinvaras I'm fully convinced that a lower, more minimal running shoe works well for me and the very small differential (drop) between forefoot and heel has strengthened my calves and ankles. Despite being a video-documented pronator I've had few troubles running in this neutral shoe. My dilemma these days is choosing a different shoe than the Kinvara when running on hard surfaces.

I love the Brooks GTS-10's that were my go-to show prior to acquiring the Kinvaras. Ironically, although I have seven pairs of running shoes I really don't feel like I have that many choices. My Helly Hansens are great for tough trails but not a shoe that I like to wear on the road. My Adidas Responses work well on vacation, doing double duty as a trail or street running shoe and also for walking. But as a daily trainer they are just built too high. That leaves me with the Skecher's Resistance Runners (at best an occasional training tool), the Karhu Fast 2 Ride (a good shoe but not for me) and the Saucony Grid Tangent (a light stability shoe whose only negative is its conventional build). Finally, the higher platform of the Brooks has discouraged me from pulling them out of the cabinet as often as did in the past.

Last week I stopped by City Sports and tried on the Merrell Trail Glove, a zero-drop minimal trail shoe. I loved its wide toe box and light weight but my foot felt off balance toward the front. I want to try the NB Minimus next, as well as the Brooks Green Silence and the new Saucony Mirage. I'm concerned that I'll soon wear out the Kinvaras and I'm definitely going to replace them with something as minimal. I love to try out new running shoes but I've really learned to love the Kinvaras. I look forward to struggling with that decision.

Running shoes: Less is more (and more are coming soon)

An interesting line of minimalist shoes coming soon from Merrell

Today's run (street): 3.85 miles

I'm really loving the blog Minimalist Running Shoes where they review some of the lesser known brands and models on this eponymous site. Like the shoes they cover, the site is simple, with a handy method of rating the shoes against a number of criteria. I just read about Merrell's upcoming (for 2011) line of "barefoot" running shoes: the Trial, True and Tough Glove models. There are also woman's versions called Pace, Power and Pure. There are many minimalist shoes on the market or coming in 2011 and this conflicts me greatly. I already own seven pairs of running shoes (plus a few pair of retired trainers) and it's hard to justify another purchase.

I've been fortunate to acquire a number of these pairs through the review process so that's another channel to pursue. I love the Saucony Kinvaras that have helped me transition to a more neutral, mid foot, style of running and the smart thing would be to buy another pair after my current ones wear out. However, if I do that I won't have the opportunity to try the Merrell's, the New Balance Minimus, the Brooks Green Silence and a bunch of other minimalist models that sound compelling. Borrowing from that old cliche: so many running shoes, so little time.

This morning I went for my third run with the Karhu Fast 2 Fulcrum Rides. My plan was to go out normally and adjust my pace with the conditions. I started out well and the shoes were fine, although I do wish the differential between the heel and front foot was smaller. The mid-sole is chunky and that helps with impact with a mid-foot strike but I've become used to a lower riding shoe. I ran in my Brooks on the treadmill yesterday and while that has a fairly built up heel, the GTS 10 feels more stable. I enjoyed the run for the first few miles. It helped to be back on the street in the cold (but not frigid) air. I did need to be careful in some spots where snow, ice and slush remained on the road. I stayed hyper alert for cars and trucks on those narrow sections but happily there were no close calls.

By the end of the third mile I began to tire and worried that I may be getting sick. The anniversary of last year's illness and the multiple times I've caught the flu during the last week of the year make me a little paranoid. I finished just shy of four miles. I'm mildly concerned that I've lost a little base conditioning over the last few weeks but I'm certain it's related to other factors. My hope is to do at least one more long distance run before I return to the office next week. In the meantime I've been focusing more on getting in a few extra daily miles during this week.
