Feel the perfect harmony of fit, feel and performance with your new Balega Hidden Dry Sock - now made with recycled Drynamix® for a lighter footprint! Enjoy improved ventilation thanks to additional mesh paneling on the top of the foot. At the heel, you get the unique triple-Y design for an ergonomic fit that locks you into the deeper pocket. The reinforced microfiber heel and toe add durability while the heel tab helps prevent slippage into your shoe. Thanks to the low volume, thin construction, this is the lightest performance sock on the planet.
