This is actually my second pair, but it was my fault because i brought a 9.5 and needed a 10. i usually wear size 9.5 in shoes and i usually buy a 10 in boots. The reviews said exact size but i needed a half size bigger, probably because i have wide feet and it's still a little close but they feel great on my feet. I haven't worn them outside yet but from what i see and feel i have high hopes.appear waterproof, but not sure. will update because i'm going to find out.
