I love Clarks and have many pairs in different styles. I love how these looked and they were comfortable, but they were too big. I always wear a size 10M. Based on many reviews (both here at Amazon and other websites), I ordered down a half size--but they were still too big! These were more like an 10.5 or 11 I guess. My heel would come out of the back with each step. I tried it on with trouser socks, if that helps you judge. I was disappointed to return them.
