Since Revain or Merrell don't post the correct picture of men's water sandals in black, I posted my own. I usually wear a size 10.5 open toe Crocs and ordered a size 10 (because 10.5 was out of stock) and they fit my foot perfectly! I have flat feet so the instep support helps and feels comfortable when I walk for a long time. They feel a bit slippery at first on smooth surfaces, but you just have to break them up a bit. In general I am very happy with them.
