Hidden Dry Re-Engineered No Show Tab is a lightweight, super-thin running sock for all-season training. Crafted with Balega's Drynamix moisture management fiber, which retains its performance throughout the life of the sock, the socks keep feet cool and dry while allowing free airflow for maximum comfort, performance, and durability. Re-engineered from previous versions with a reduced waste design, the socks feature less excess material and fewer exposed threads to increase comfort and provide lighter weight feel. These socks 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 toe and heel to create a more formed, extra-deep heel pocket to anchor the sock around the heel to prevent slippage. This unique design ensures that each sock fits your foot properly and does not slide down into your shoe during activity.
