The Smartwool Men's PHD Pro Freeski Socks are pro freeskier Angel Collinson's signature sock! These socks were built with the Indestructawool™ technology for enhanced durability, the 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.
