I was cleaning out my closet recently and decided that I must bite the bullet and rid myself of some running shoes. Running as much as I do, I go through a LOT of shoes. But not as many as I should. I should probably have twice as many if I put only the recommended milage on each pair. But I just find it hard to buy new pairs until the old ones are physically hurting me. Some blow out, but others just collapse. It's those that are dangerous cause I run far further on them than I should. This pile has lasted me for about a year and a half. Whoever said running is free, is a LIAR!
