About this item
- MAXIMUM MOISTURE AND SWEAT MANAGEMENT: Our signature Olefin fiber is a light-weight, high-performance fiber that wicks moisture and dries quickly, so your feet stay dry and blister-free wherever your adventures take you.
- THIN, BREATHABLE DESIGN: Upper channels and a mesh footbed are thinly knitted for ultimate breathability and ventilation to prevent hotspots and keep your feet cool.
- FIRM SUPPORT: Our highest compression sock with arch band support that hugs your feet firmly to support your muscles and reduce fatigue so you can perform better, longer.
- Y-SHAPED HEEL: Heel is stitched using a Y shape for a snug fit that moves with your foot without any bunching or slipping.
- New Micro Tab prevents contact with the back of your shoe to protect your heel.
