We borrowed the polar bear’s ingenious heat-channeling capabilities in developing the thermolite fabric that makes this ski sock so exceptionally warm. And because wet feet equal cold feet, the Winter Ski is outfitted with Omni-Wick technology for highly breathable, moisture-wicking comfort. Beefed up padding in the shin area protects you from boot bang, while a seamless hand-linked toe banishes pressure points and abrasion. FEATURES: Fabric: 82% thermolite polyster/16% polyester/2% elastane, Seamless hand-linked toe, Padding in shin for fit and protection, Omni-Wick advanced evaporation, Arch band for fit, Flex stretch in ankle, Reinforced heel and toe, Imported,
