I had ordered a half size smaller than my normal size and it was still a little bit to big for me.  Overall it looks good and works ok but we were using it at the beach and it constantly filled up with sand and became uncomfotable.  The inner lining would move around under my feet when I was in the water, I think this may have been because it was a little bit too big and once sand got between the lining and the inner sole of the shoe the lining would no longer grip.

This item is priced well and i think the problem is more that I bought the wrong type of water shoe for my purpose - I should have bought a fully enclosed one.
