You won't even know it's there.


When you find a truly good sock you won't even notice it's there. You'll forget all about your Smartwool Women's PhD Ski UL USA Socks while you're cruising through sunny slopes and exploring backside bowls, surrendering to the magical freedom of sliding down snow on two planks of wood. These ultralight socks sport a merino wool, nylon, and elastane construction that resists odor for repeat wears and breathes well during spring ski missions. The 4 Degree Fit System keeps your socks from bunching in your boots and the seamless toe eliminates irritation for long days on skis.
