Supinating is how I roll

Today's run (street): 4.3 miles
Yesterday's run (street): 5.1 miles

Fall is almost here and I'm loving the cooler temperatures. Unfortunately, the humidity still thinks it's summertime. That's true, but running conditions have improved over August's dog days. Stepping out to mid-60's temperatures provided a welcomed boost this morning. I had two good runs this weekend, even though my positive performance from Friday wasn't duplicated on either day.

Yesterday I broke out of the boundaries of my neighborhood, venturing into the nearby business park and the neighborhood that connects to it. I'd targeted 5 miles and ran easy. That turned out to be a good idea because the humidity was an oppressive 88%. This morning felt cooler and a moderate breeze from the north provided a nice offset to still-present humidity. I'd considered a trail run but didn't want to deal with mountain bikers at Stillwell. I ended up staying local.

The best thing about today's run was that my energy level was running a few notches above usual. Feeling stronger prompted me to step up my pace and open my stride. It was during my run on Saturday that I noticed how my form has changed since dealing with my herniated disc. I still have slight discomfort in my left thigh, especially when I push my speed.

After yesterday's run, I looked up strides and landing styles and realized for the first time that I am actually not a pronator. That label was given to me seven years ago by the salesperson at Super Runner's in Huntington after she watched me walk across the store. That resulted in my purchase of a pair of Brooks Adrenaline 9's that I loved dearly and wore for 1,000 miles.

Although pronators are supposed to wear stability trainers, I've always felt comfortable running in neutral shoes, especially the minimal variety, That explains my love for the Kinvaras and my appreciation of the Saucony Virratas that I recently replaced with the Kinvara 5s. The article I read showed wear patterns and connected them to different types of strides: pronator, over-pronator, neutral and supinator.

According to the illustrations, I'm a supinator, someone whose foot rolls outward on landing. I looked at my Virratas, the shoes with the most outdoor mileage, and the wear pattern clearly shows that I do this. So now I'm confused. Stability shoes are built with a medial post or some type of multi-density material in the mid-sole to neutralize inward rolling. I get that. What I don't get is when I look up "best shoes for supination" most results point to stability shoes. But since it's the opposite problem, wouldn't stability shoes amplify supination?

While the running world works to figure that out, I'll stick with my minimal neutral models. The only downside to that is my preferred shoes use a fairly soft material on the out-sole that is apt to wear out from all my supinatin'. Still, I'd rather run in shoes that feel right, rather than ones that are made for people who supinate. So far, that seems to be the right approach.

Kinvaras as a daily trainer?

These cool Kinvaras are becoming my everyday shoe
The transition to fall weather makes me happy. Although it will take some time to adjust my running gear so that I don't go out under-dressed like yesterday, I still welcome the change. This morning the temperature where I live is 51 degrees, perfect for a run but quite chilly when standing on the train platform. I always wish for this weather when enduring the heat of summer or the frigid cold in January. I'll enjoy it as long as I can.

I wore my Saucony Kinvaras during yesterday's run and I've started to really appreciate them. Lightweight but not insubstantial, they are minimally constructed but still reasonably supportive. The Kinvara is a neutral shoe and I thought I'd have trouble with it because I pronate when I run. I've had some 8+ mile runs with them without experiencing any problems with my knees or legs and that brings me to question the idea of stability shoe engineering. I suspect that because the drop off between heel and forefoot of the Kinvara is only 4mm, compared to 12mm, (common for standard trainers) the shoe facilitates a more natural mid-foot landing. This would logically neutralize the effects of pronation. I continue to rotate through my other pairs and still consider my Brooks GTS 10's my everyday shoe, but the Kinvaras are forcing me to rethink that these days. If I do move primarily to the Kinvaras I'll need to consider their durability and the thermal properties of the barely-there uppers compared with the Brooks' more substantial build. After all, it's getting colder out there these days.
