Subject: Small Tears or Holes on Running ShoesI have developed these small holes on the inside of the shoe where the back of the heel that is just below the achilles comes in contact with the shoe. I've put about 100 miles on them so far. When I take off my shoes, I untie them rather than just kicking them off my feet. How is this caused and should I be concerned? The shoes are Pearl Izumi Synchro Guide 2s. I love the shoes, by the way. I switched to them on a hunch from a model and brand of shoe that I had been loyal to for many years; the Pearls are primarily responsible for almost eliminating the PF pain that I have suffered with for about a year and a half. |
