Perform under pressure thanks to the CW-X Ventilator Compression Support Sock. From your toes to your calf, these socks offer gradual compression that reduces the build-up of lactic acids, so your muscles require quicker after a long day on the trail. Lightweight synthetic materials breathe easy, while mesh ventilation on the top of the sock allows heat to move away from your skin. CW-X shaped these socks with a flexible toe box, and in order really drive your performance home, a unique web of materials offers additional support to your ankle and arch.
