The 14k performance skate sock is the most advanced skate sock on the market today. Constructed with 77% olefin, 20% polyester, and 3% spandex this sock gives you the warmth in your skate without the heavy feeling like a wool sock. Olefin fibers are designed to wick away moisture from your feet during play while at the same time keeping it's strength in wet or dry conditions making this sock very resilient. In the 14K there are two types of zones: the first are compression zones that provide a high level of support reducing foot fatigue and aiding in circulation, the second is anti-slip zones which prevent slippage inside the skate therefore ensuring a proper fit which ultimately lengthens the life of the socks. Reebok put a lot of thought into these socks so you can focus on nothing but your game.
