Smartwool Womens PhD Outdoor Heavy Crew Socks

Size Chart

Smartwool's SW001076 PhD Outdoor Heavy Crew sock for Women provides serious warmth and high-density cushioning, yet also gives us a fit that is never bulky and can be worn comfortably with causal and athletic shoes alike.

The addition of Indestructawool construction means these socks last longer. Like all Smartwool PhD socks, the Outdoor Heavy Crew promises a high-tech fit (this model includes the 4 Degree Elite Fit System which uses a elastic network to guarantee greater stretch and recovery) to comfortably keep your sock in place all day. The Heavy Cushion Outdoor Crew sock from Smartwool has a bump-free, virtually seamless toe seam for longevity, and comfort. Mesh Venting promotes breathability and moisture-management.
