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.

With more than 2,000 specialty retail partners across the U.S., OS1st is proud to serve communities that prioritize movement, wellness, and living life on purpose.

Our story behind Socks with Purpose is about redefining how we perceive something as simple as socks. Every pair we create undergoes rigorous wear testing and garners extensive feedback from consumers, athletes, and medical advisors. This meticulous process ensures that we deliver the perfect product to you.

Socks with Purpose embodies our commitment to creating innovative products tailored to every unique foot type. Our goal is to meet your needs with a deep level of care and empathy that sets us apart.

At OS1st, our goal has always been to innovate new products and technologies to help people manage their pain and injuries. We want everyone to feel better for longer.

When realizing that the market was filled with heavy, hot, expensive, and hard-to-wear solutions, our founder, Dave, drew on his experience knowing that there had to be a better way. That’s why OS1st developed lighter, easier-to-use compression technology—and went even further by making it comfortable.
