I bought a pair of these at a local sports store. I just wore one pair and my feet were incredibly warm for a FULL DAY of skiing. I did not use feet warmers once. So, I immediately went on Amazon and bought two more pairs. The padding in the front of the sock is just enough to prevent my ski boots from rubbing and the material is amazing, the wool soft, not scratchy, breathable, warm, and no smelly feet from sweat! To anyone who values warm feet BIG TIP: only wear one layer of quality socks like these. When your feet have proper circulation with just one pair of socks with a material that can wick away sweat, that is all you'll ever need!
