Shoes OS1st Socks

OS1st is a performance wellness brand on a mission to deliver Relief You Can Feel. We design purpose-built socks and compression bracing that support the way people move—whether they’re training for a race, recovering from injury, or simply trying to get through the day pain-free.

At the core of our brand is Socks with Purpose®—a collection of anatomically designed, high-performance socks created for specific needs like plantar fasciitis, bunions, swelling, sport, and recovery. Every pair is crafted with medical-grade compression zones, moisture-wicking yarns, seamless construction, and a left/right-specific fit to provide real, tangible relief from the ground up.

Our compression bracing sleeves apply the same intention—targeted support with minimal bulk—to the knees, ankles, wrists, and more. Developed using sports medicine principles, they’re trusted by healthcare professionals, athletes, and everyday movers alike.
