If your feet sweat even a little bit, these shoes are not for you. First lets talk about the pros, the fit snug and helps you to keep balanced. Now the Cons, there is no ventilation on these shoes, so with or without socks your feet sweats. I have a desk job and my feel were sweaty, so these are not for people who do a lot, they are comfortble, that is the only reason I gave them 3 stars, other than that I would have given them 2. I wish I can send them back, I just purchased them 1-2 weeks ago, because I would.
