These fit well and are very comfortable. I was afraid that the back of the heels would chafe against my ankles but they don't. They also float! - which is a big plus on the water. The problem with them is that the outer soles started, well, disintegrating is the best way to describe it; they leave little bits of rubber everywhere I walk. It's not a big concern on the water, but I wanted to wear them on a houseboat and have to vacuum everywhere I go, lol :\.
