The Smartwool Snowboard Targeted Cushion Piste Machine Over The Calf Sock is a long sock designed for snowboarding. The targeted cushioning makes every snowboard adventure even more comfortable, adding cushion to the front of the shin, bottom of the foot, and back of the calf, while body-mapped zones elsewhere increase breathability. The yarn is a Merino wool, nylon, recycled nylon, and elastane blend for ultra softness, odor resistance, natural temperature regulation, and durability. Slip each foot into the pair and take on the mountain with toasty toes.
