Not exactly heart insole

I was really hoping to publish today's post with the headline "Heart insole, I fell in love with you" after running with a replacement pair of insoles for my Nikes. I've been concerned that my shoes have accumulated too much mileage and that has contributed to the leg pain I've experienced over the last six weeks. The shoes still look pretty good so I don't know how to ascertain their true condition. Since the insoles, which take direct impact with every step, are easily replaced, I did just that.

The insoles I bought are Spenco Poli-Sorbs that retail for about $20. They come in size groupings so you can cut the extra material for a custom fit. I didn't do that and I suspect that's part of the reason I was disappointed.

Though I wear a 10 1/2 shoe and these insoles fit up to size 11's I was able to fit them into the shoes fine. The shape of the replacements are different than the originals but they're close. When I put them on they felt good, the extra padding at the heel was welcomed. There was slightly more material at the top but it didn't seem like it would get in the way when I ran.

I had a hard run covering 2 miles at about 8:52 per mile this morning. It was extremely hot and I suffered a bit until getting an energy boost at around 1.5 miles. The shoes felt okay as I ran but my upper leg pain was noticeable. Unlike when I ran with the other insoles, the pain persisted even after I'd warmed up. After I'd finished I noticed that the extra material had put enough pressure on the top of my foot to cause some slight abrasion and blistering. I can take care of that by trimming the insole but the real problem was that my leg hurt a lot after my run. I ended up wrapping a compression brace around my upper leg and that helped quell the soreness.

Now I'm wondering whether I'm better off cutting the insoles for a perfect fit and trying another run or just reverting back to the old insoles and hoping for the best. The race on Saturday is only 5K so it's not like I need to prepare for an arduous distance. The other choice is to run in my NB trail shoes. That's starting to sound like an interesting idea.
