It was slightly larger than the size I usually wear. Definitely super, very comfortable, the material feels nice. Sometimes when I get out of the shower and put them on there is VERY STRONG suction and that's an impressive amount of power to lift. The only thing I don't like and that's partly just a part of life. When worn in a warm or hot environment. Your feet stay cool no matter what, but your feet smell stronger than usual. They have vents at the top, but it's the bottom of your foot where heat and sweat collect and brew. I have found that the best way to reduce this effect is to wear socks. For this reason, I simply avoid them for a long time on warm days.
