Micro Crew socks are slightly shorter than traditional crew height socks, fit to just above the top of a standard high top hiking boot, and have become the preferred sock height for many people while wearing all types of hiking footwear. This midweight cushioned version from Darn Tough features targeted terry loops underfoot and just above the ankle. Darn Tough socks have become the favorite of many of our staff and customers, and are known for their excellent performance and longevity. Darn Tough socks are guaranteed for life, and they ask all customers to contact them directly for replacement if anything goes wrong with their Darn Tough socks.
