Balega Hidden Dry No Show socks are engineered to a lightweight, super-thin running sock for all season training. Engineered with Balega's 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-tested 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. Balega launched in 2003 and set out to create the world's best performance running sock. Built to perfection, Balega socks are composed of extra fine yarn on high needle count machines to provide plush and protective cushioning, without adding bulk. Each pair of socks are hand-linked for a fully seamless design and feature a moisture management fiber, Drynamix, to keep feet dry and cool. Balega socks are hand inspected for quality assurance.
