Sock Geek Says:

Versatile enough for both road and off-road but we like it on the trails best.  High density, not bulky, cushioning on foot bottom with open mesh knitting on top of the foot for maximum breathability. Ribbing above the ankle ensures a proper fit and keeps rocks out. Reinforced heel and toe box support Darn Tough's legendary reputation for durability. Elastic support around the arch secures the sock to the foot eliminating twisting that can cause irritation and blisters. Ring toe construction delivers a comfortable, invisible seam that reduces toe abrasion. Merino Wool provides terrific moisture management and great anti-microbial properties to control foot odor. Premium raw materials and exacting quality standards make this a sock that delivers comfort and performance where ever you use it!
