Changes

As you may know from my previous post on primal running shoes, I modify my Nike Free shoes. The Nike Free is an ideal starting point running shoe for modification. Instead of a separate cushioning midsole and a hard rubber outsole, the Free combines the two into a single layer. This cushioning is much tougher than a conventional shoe, so it withstands the abrasion without an outer sole. Modifying a conventional shoe requires removing the outsole, cutting away at the midsole, then reattaching the outsole. With the Free, you just remove what you don't want. (Note that I use the Nike Free 3.0.2 as the starting point.)
