An all-time best-seller. Whatever your activity is, we have the Women's Merino Activity Crew to meet any need. This is a sock you can wear for days. We're lucky to use American-sourced merino wool that's soft, warm, and moisture-wicking, making it also inherently anti-bacterial. The interior of the sock is terry-knit with big loops of soft yarn that create a padded layer for comfort. This is a rugged boot sock, but it's not too thick to be in a standard shoe, too. This one is made specifically for women, but you will also find a men's fit here.
