This flat knit sock provides a close, lightweight fit that acts like an adventurer's second skin to minimize friction and blisters. Use with a second sock when extra warmth and protection is needed.

The Smartwool Hiking Liner Crew can be worn as an ultra light sock on warm hikes or as a liner in cold weather. The ribbed cuff keeps it from sliding into your hiking boots or bunching at the bottom of your outer-layer sock. A flat-knit toe seam won't bother your toes while breaking trail. Smartwool designed the Hiking Liner Crew Socks to prevent blistering as well as odor—feel free to layer without fear of grossing out your camping buddies.
