Put on the same sock that pro freeskier Angel Collinson wears with her signature sock, the Athlete Edition Freeski Over the Calf Socks. Using Collinson's insight, we built these socks with our Indestructawool™ technology for enhanced durability, our 4 Degree™ elite fit system for a dialed, performance-oriented fit, and our Shred Shield™ technology for reduced wear from toes. Its design includes contoured shin and ankle cushioning with a flat knit toe box, as well as a wider welt for a secure fit and comfort. You won't get to Angel's level of skill without practice, but putting on the same sock that she chooses to wear is a good place to start.
