Size L (US9 - US12) Extra cushioning protects your foot and leg from the bumps and jolts of a long tour. Moisture-wicking keeps your feet dry and comfortable, while a sure fit means no annoying slippage and bunching. Our exclusive Wick Dry technology keeps feet dry while Scentry technology reduces odor in the sock. Heavy cushioning for longer activity, extended trips and cold weather. 76% acrylic, 22% nylon, 2% spandex Our exclusive technology quickly draws moisture away from your skin so your feet stay dry and comfortable. Removing the moisture build up reduces hot spots and friction that causes blisters. Sock-specific mesh and vented panels provide breathability and help manage moisture to keep feet dry. Scentry helps permanently defend your socks from odor. Natural and man-made agents make this technology a sure way to be confident about sock odor. This is accomplished by an embedded fiber like silver or copper or with a micropolymer silane technology which slows wear and reduces odor in the sock. Special zone cushioning at the instep reduces lace and tongue pressure from your boot or shoe. Heel and toe are reinforced with nylon to add durability and longer sock life. Smooth, flat toe seam doesn't rub or irritate during wear. Plus, our smooth, flat toe closure technique adds durability so it stretches every way you do without unraveling.
