I wear a 8, so that’s what I bought. As soon as my feet get warm these shoes stretch. Big time! They make more noise than flip flops!!!! You can hear me walking down the hall sooner than you can see me. Lots of cushion and very comfortable, until my feet start sweating and a small unbreathable swamp gets created in my shoes. Less than a month later these are in the closet. I wouldn’t buy them again. They didn’t hold their shape well and now look silly and lumpy. Back to danskos please.
