These are as fantastic as everyone says they are. I will say though that the sizing is a little off. I wear a 9 or 9.5 in women's shoes and the Large fits perfectly. I tried on an extra large in a store (since that's in line with my normal sizing) and there was a lot of extra space in the back fo the sandal. I'd say you don't need to get XL unless you wear a 10 or above.
