Using insights of pro skier, gold medalist, and Smartwool athlete Mikaela Shiffrin, we constructed her signature sock, the PhD® Pro Ski Race. 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 cushioning, as well as a wider welt for a secure fit and comfort. The newly engineered arch elastic helps enhance ski feel and in-boot fit. When you wear what the pros do, it helps you perform like them too.
