Not too long after the conclusion of the race, I drove out to Hood River in the Columbia River Gorge to purchase a pair of Sprints, and I absolutly love them! I wear them almost everywhere I go, except for work. They feel just as though I am barefoot.
When I first got them, I noticed my feet feeling a little sore, but it wasn't that I was injured, I was using muscles that I wasnt used to using. I also started out by running no more than 2 or 3 miles in them, and my feet toughened up nicely. Now I can walk around in them all day on concrete and not feel sore, or I can even run on asphalt and not leave a good amount of skin on the track.
I still only train in them twice a week or so, and I havent run more than 13 miles in them, but I have definatly noticed an improvement in my running form, and alignment issues. Also, you should see the looks I get when I walk through the mall in those things!
Well, until next time, keep on running.
