I already had two pair of this particular pair of shoes (different colors) and they fit like a glove, so took a chance on these.

Unfortunately, the pair I received were much larger (nearly a full size), so had to be returned.

Nevertheless, if you can get these to fit, they are the closest thing to going barefoot (but still having the support of a shoe) that I've ever experienced.  They are especially comfortable for people who have a bunion, b/c the sweatshirt fabric stretches to accommodate any foot shape/need.

This shoe often turns up in places like T. J. Maxx, so my advice would be to find a pair to try on before buying.  Or take a chance on ordering and then return them if need be.  Amazon's return policy is fair and easy to activate.
