Sock Geek Says:

High density, not bulky, cushioning on foot bottom absorbs road shock. 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 issues. 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.
