Designed Around the Mechanics of the Human Foot
The human foot contains 26 bones, 33 joints, and more than 100 muscles, tendons, and ligaments, making it one of the most biomechanically complex structures in the body.
Despite this complexity, the sock category has traditionally overlooked the role socks can play in supporting foot mechanics.
OS1st approaches product design differently—treating socks and compression products as functional performance equipment rather than simple apparel.
Drawing on principles used in medical-grade compression and orthopedic bracing, OS1st engineers targeted support into products that enhance natural movement and athletic performance.
Today the brand offers a full range of:
- performance socks
- targeted compression sleeves
- recovery solutions
- activity-specific designs for running, court sports, hiking, work, and everyday use
Each product is built around the same core philosophy:
Support the body’s natural mechanics so people can move better and longer.
Our Origin
OS1st began in Hickory, North Carolina, a historic center of American hosiery innovation.
Founder Dave Higgins spent decades leading and consulting for major sock and textile manufacturers. When his wife developed severe plantar fasciitis, he applied that expertise to create a solution that traditional socks and braces could not provide.
The result was the FS6® Performance Foot Sleeve, a targeted compression product designed to support the plantar fascia and redistribute pressure across the foot.
What started as a solution for one problem quickly revealed a bigger insight: The foot is one of the most biomechanically complex parts of the body—and most socks ignore it entirely.
OS1st was created to change that.
What Makes OS1st Different?
Engineered Support™
Unlike traditional socks that function as simple fabric tubes, OS1st products are designed using Compression Zone Technology® to apply specific levels of compression in targeted areas of the foot and lower leg.
This allows the product to:
- optimize natural foot function, including toe splay
- support muscles and connective tissues
- stabilize key structures of the foot
- promote circulation
- reduce fatigue and swelling
- improve overall comfort and performance
Instead of compressing the entire limb equally, OS1st products deliver support where the body actually needs it.
Engineered Support for Every Step
OS1st is a performance-driven brand specializing in advanced socks and targeted compression technology designed to improve comfort, support natural movement, and help people stay active longer.
Born from decades of hosiery innovation and biomechanical insight, OS1st products are engineered to support the foot-sock-shoe interface, one of the most important yet overlooked systems in human movement.
From runners and athletes to healthcare professionals and everyday movers, OS1st helps people perform better, recover faster, and move with confidence.

Dave Higgins
Founder
After seeing his wife struggle with Plantar Fasciitis, our founder, Dave, used his knowledge from a long career in socks and hosiery to invent a compression solution to soothe her feet. That product, the FS6 Performance Foot Sleeve, was our first product and revolutionized the compression industry. Today the company still runs under the Higgins family with Josh Higgins, as President.
