With a low-profile design and secure fit, the Balega Ultra Light No Show Socks offer a barely-there feel that is ideal for running in snug shoes or warm weather. Snug support around the arch and ankle fit like a second skin and sculpted mesh panels add excellent ventilation. Balega's seamless toe prevents blisters, the rear tab stops slipping, and thin reinforced cushion at the heel and toe enhances comfort and durability.
