Whatever your activity is, whether it's hiking on the trail, riding on a bike, or working in the yard, these socks will fit the bill. Made from merino wool which is soft, warm, and moisture wicking, with added anti-microbial silver in the heel and toe to really kill the odour. This is a sock you can wear for days if needed. The interior of the sock is terry knit, with big loops of soft merino that create a nice padded layer of comfort and warmth. This is a rugged style boot sock, but it's not too thick, it will fill out your shoes or boots without crunching your feet.
