A zoned knit structure provides firmer support around the ankle and gradually transitions toward the calf for a secure athletic fit.
High-stretch ribbed cuffs help keep the socks in place without excessive pressure around the calf during extended wear.
Tightly knitted nylon-spandex fabric helps move moisture away from the skin and promotes airflow during running, cycling and hiking.
Elastic support around the midfoot follows the natural contour of the foot to reduce shifting and bunching inside your shoes.
Higher nylon content in the footbed improves wear resistance, while structured zones add cushioning and stability during repeated movement.
