Horrible the back strap is too short. I will be returning these. 6/13 Update.... I contacted Crocks, customer service and was told that the back strap should not be that short. They asked for proof of purchase and to have the tags on the unworn clogs and they would issue a a return authorization # and will send me a replacement for the defective ones. After that I have also purchased additional pairs from Crocks the strsp is normal. I noticed that the ones purchased on Amazon were made in Mexico apose to the ones purchased from Crocks that were made in Vietnam.
