Balega Hidden Dry No Show socks are engineered to a lightweight, super-thin running sock for all season training. Engineered with Balega's proprietary Dryanmix moisture management fiber, the socks keep feet cool and dry while allowing free airflow for maximum comfort, performance, and durability. Hidden Dry No Show socks have been race-d and incorporate a hand-linked seamless toe, which eliminates abrasion across the top of the foot and provides ultimate comfort. Ensuring a perfect fit, these socks feature a contoured, low volume construction, complete with a reinforced microfiber to and heel to create a more formed, extra-deep heel pocket. This unique design ensures that each sock fits your foot properly and does not slide down into your shoe during activity. 1-year warranty.
