Made with advanced Indestructawool™ technology for enhanced durability and the 4 Degree™ elite fit system designed to eliminate slippage, bunching, and blisters… for a peak-performance fit the Smartwool Ski Zero Cushion Print OTC Sock is everything you’re looking for in that smoothly fit technical sock that glides into your boot without distorting the feeling of power and control you get with a custom fit. Body mapped mesh zones give you extra breathability where you need it, and the OTC height brings the sock up to mesh with calf length baselayers for a fit at the top of your boot as clean as the one inside. When you want the most from your gear it’s often the little things that make all the difference and the right sock is the right start.
