Everything about this sock was created to work seamlessly with a high-performance boot: strategically placed cushioning on the heel and toe, light shin cushion, non-cushioned heel and toe, and all the benefits of Merino to help keep you warm and dry. The 4 Degree® elite fit system creates a dialed fit and Indestructawool™ durability technology delivers long-lasting wear. A women's-specific fit creates a narrower heel and overall slimmer fit.
Don't let the cold stop you from taking one last run: the PhD® Ski medium delivers maximum warmth and breathability when the going gets cold. Patent-pending Indestructawool™ technology provides ultimate durability to make sure your socks are ready to go, run after run. Made with our 4 Degree® elite fit system for a sock that doesn't bunch, slip, or bind and a women's-specific fit for a narrower heel and overall slimmer fit.
