I didn't purchase these at Amazon; in fact I got mine from an off-price seller at about half off retail. I echo previous reviewers' comments that these shoes have a good strong arch support and are perhaps best for those with a high arch. I have a wide foot with a high arch, normally take a size 7.5W or 8M, and found the 7.5 wide to be an excellent fit without socks. I've also worn them to the gym with socks, and they're just a trifle tight.

These shoes have a tag which describes them as "water ready", and that is essentially true, even if these may not be the best choice for water shoes. They are leather-free and made mostly of mesh, with drainage holes. But the sole is a single piece which lacks drainage, and although the insole is removable these are not quite as quick to dry as my pair of Salomon water sneakers. Nevertheless, if I were going on a longer trip, I'd be happy to have both pairs with me, and let one dry while I wore the other.

Overall this is an excellent shoe. But considering its appearance in the off-price seller's store (and I've seen it in similar off-price websites as well) you may wish to look for your size at a better price.
