The Willoughby hiking sock might be named after Vermont’s most insta-spammable lake, but the real influencers are the sure-footed critters paddling across its buttery-soft, ribbed cuff. Dip into these lightweight Micro Crew height socks, knit with climate-controlling Merino Wool and cozy cushion underfoot, and you’ll be trekking on without fear of the dreaded swamp-foot that can lead to blisters.
Unrivaled Durability
We make one thing, and we make it better than anyone else – ask any thru hiker and you will likely hear the same. In order to unconditionally guarantee a hiking sock for life, it must be durable. It must maintain its comfort, and it has to fit for miles upon miles on-trail.
Cushion
Cushion in the Hike/Trek category features terry loops under the foot, and in the taller styles reaches above the ankle for comfort and protection.
Sustainability
From responsible sourcing practices to livable wages in our communities - Darn Tough Vermont is committed to progressive, positive, growth.
Care
Machine wash in warm water on a gentle cycle with socks inside-out. Do not bleach. Tumble dry on low or hang dry. Do not dry clean.
