I usually wear a size 12 but after reading some reviews saying these run large I ordered a half size smaller.  They were still to big.  Returned them with no problems for an 11.  After about 2 weeks the strings began to fray apart.  But shoe strings are not exactly expensive to replace so that did not bother me.  What does bothered me is that after a maybe 3 months the soles had almost no tread left.  I do spend a lot of time on my feet but I expect shoes to last longer than a few months.  I will not buy this product again.
