The 20K socks provide an extra layer of protection. Made in part, with Dyeenam fabric, the world"s strongest fiber, is a low weight and abrasion resistant fiber which provides excellent protection against cuts, without any compromise on comfort. This serves as a base layer of protection, or put another way, a back-up plan should your shinguard wrap fail. The second key to the 20K Protective Skate Sock"s performance is the use of Copper within the fabric. Copper is well known for its anti-odor, hygienic protection and skin wellness for the wearer. This helps keep viruses at bay, odors to a minimum, and also helps prolong the life of the product. Combined these two yarns are strategically woven together to form the full scope of the 20K socks; a tight-fitting sock, specifically designed for the hockey player and skate boot. Your feet will feel better during play and you"ll also notice less sliding within the boot when compared to standard apparel socks. Maximize your safety and skating performance with the 20K Protective Skate Socks.
