Customer Reviews

Comments: Surprisingly lightweight. I tried them out in the high teens and my feet were cold at first but warmed up once I got running. Sweating oddly seems to make them warmer rather than colder. Good for below freezing temps but for anything lower than 18 deg or so I'd go with something heavier.
