I purchased these for my boyfriend for our upcoming beach trip and he loves them. He's normally a size 10.5 so I was concerned that the 10 would be too small and although they are slightly snug; they should work just fine when in the water. He wore them around the house to break them in and so far no issues. We both love the styling of the shoes as well. They are definitely the best looking "water socks" available and totally worth the extra cost.
