Used by veteran climbers, backpackers, and trail runners worldwide, the liner sock creates a friction buffer between the foot and outer sock. Assuming there is adequate volume within the hiking or running shoe, this additional layer takes the brunt of any rubbing, not your foot. The SmartWool Hiking Liner Crew sock is a great option for trying this technique. If you're suffering from blisters and hot spots, give this solution a try. Also, the SmartWool Hiking Liner Crew provides a touch more warmth for cold conditions.
Perfect lightweight sock
I got these to take on a trip to Europe as my "everyday" socks - and I couldn't have asked for a better product. Lightweight and comfortable with different shoes, these will be a staple in my wardrobe!
Great Sock
I love Smartwool, and these socks lived up to my expectations. Nice as a thin standalone sock, size fit as expected.
Good value
Not a bad sock for the price. Good as a thin, stand alone or as a liner. Very comfortable. Haven't owned them long enough to say how durable they are. I wear an 11 & they fit me a little loose; I think smaller feet would swim in the size large.
