The OS1st Thin Air Performance Socks are must-haves if you need performance socks that will keep your feet cool on the run! On top of the blister prevention that you expect from a good pair of running socks, these socks are made using OS1st's Skin Thin Zones Technology with ultra-thin materials and lift-bars, air flow is maximized around the foot, preventing overheating. Four discrete zones of graduated compression help to promote circulation, keeping your feet healthy on the run and assisting with active recovery. The socks are both moisture-wicking and anti-microbial, ensuring that they prevent blisters, cut down on odor, and don't bunch up during use.
