I bought a pair of these while on vacation. They were so amazingly comfortable I bought another pair from Amazon as soon as I got back.
Seriously the most comfortable "shoes" I've ever worn. They feel like bedroom slippers. And, they look great with jeans or shorts.
I normally wear 9 1/2 or 10 depending on the shoe. So I got the 10's. And although they seemed rather snug when I first put them on, they do stretch out to a very comfortable fit.
I'm not sure about durability. And, I'm not sure they're something I'd wear in winter. But, man, are my feet happy!
