Performing like the pros begins with wearing Angel Collinson's signature sock, the PhD® Pro Freeski. Using Collinson's insight, we built these socks to perform for steep descents and help lock feet into ski boots. They're also made 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.
