I have not been running in a very long time and saw these and decided to get back into it. The shoes fit kinda funny. The heel is tight but the toes have loose room. Normally I'm the opposite; I have very wide feet. By day two of running I had some monster blisters. On a positive note, I am a very large person and have not had any ankle, leg, knee, or back pain with them. In all I think I would use them again but I might order one size small to get the toes to fit better.
