Hidden Dry No Show socks are engineered to be a lightweight, next-to-skin running sock for all season training. Engineered with Balega's Drynamix™ moisture management fiber, the socks keep feet cool and dry while allowing air to flow freely for maximum comfort, performance, and durability. These socks incorporate seamless construction, which eliminates abrasion across the top of the foot, reduces friction and provides ultimate comfort. Ensuring a perfect fit, these socks feature midfoot compression for support and a reinforced microfiber toe 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.
