The outer-forefoot area of my shoes wears out far more quickly than the rest of my shoes. Within about 150-200 miles, that area of my sole is nearly bare, while the rest of the shoes look brand new. See, for example, these pictures:
Does anyone else have this problem? Do you know of a shoe that has better durability in the forefoot?
I've tried the Pegasus and the Kinvara.
You obviously supinate too much, meaning you're a whipkicker. Your foot rolls to the outside, so you push off with the outer forefoot. This could also happen if you're trying too hard to be a forefoot striker when you really aren't. When you land on your forefoot, most of the time you land on your outer forefoot. So I would recommend try switching to a midfoot strike.
I have the same wear pattern. Virtually all shoes have carbon in the heel and not in the forefoot, hence the quick wear on the outer edge. I pour Shoe-Goo on that area every 40-50 miles, or when the rubber shows noticeable wear. I run in the Pegasus, Saucony Ride, Brooks Ghost and Glycerin and adidas Supernova Glide. I can usually extend the life of the shoe to about 450-475 miles. The Goo is about $6.00 a tube.
