I've had these for about two months, and really like them. They are really comfortable, I don't find my feet getting sweaty, and they look cool too :). I noticed another reviewer said their feet went numb... I have had that problem while running, so I know I'm not immune, but I haven't had that problem in these shoes. One downside is that I was hiking steeply uphill with my bike, and the shoes rubbed my heels raw. If you stay on your bike, these are top notch.
