Our Intraknit™ Ski Targeted Cushion Over the Calf Sock will take you from the first run to the last. Its graduated cushioning and cuff shape are uniquely knit to provide a breathable performance fit without sacrificing cushion, and the extended welt offers enhanced coverage. The “butterfly wrap” cushioning at the navicular bone and ankle minimizes hot spots and heel lift, while the reinforced heels add durability where you need it most. Plus, their Indestructawool™ technology, 4 Degree™ Elite Fit System, and strategically placed mesh zones ensure a top-tier fit, all-day comfort, and lasting performance.
