Best socks ever

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I buy these socks every year. It's a thin sock for a running shoe and I really love them. Comfortable, they wear well and wash well.

Socks on Socks on SOCKS!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Guys! Icebreaker rules! I'm constantly mind-blown over how incredible their products are and these socks are not different. Considering how thin and light these are, they are ridiculously durable. I have now officially converted to all-merino wool socks, thank you Icebreaker!

Sizing was true to the sizing chart.

my new favorites

Thinner than my Smartwool socks and less fuzzy - which is great for summer. Better looking than most of the technical wool socks out there and are very comfortable.
