I've been wearing FitFlop sandals all summer long and I LOVE THOSE, so I've decided to try the clogs, I've read reviews about sizing problems but I figured I'd give it a shot and order my regular size anyway. Sizing info was specifically saying that shoe measures 10" inside no matter if it's a sandal or clog. And unfortunately I should have listened to those who warned me about size issues. They were right, they run entire size smaller. Thanks to Amazon's easy return process I was able to get it all fixed. Clogs are cute and they look comfy, just need the right size, that's all ;o)
