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.
