These shoes have hardly been worn. Gave my son bloody scratches/ulcers in the Achilles tendon area from both shoes. We have tried bandages, sports bandages, high socks, etc. to solve this problem. Whatever is rough/sharp, even cut through the toes. It wouldn't be so bad, but kids can't leave school to change their shoes. Now they are in the closet after a few uses. He told me they fit well and otherwise feel good. Was a bit unsure (14 year old) that they were clean but could handle it.
