All three generations of the Higgins' family on the steps of their office

How it started 

We were founded in 2008 by Dave Higgins who grew us into a “Three-Generation” company with his son, Josh, as President, and grandson, DK, as Operations Manager. 

OS1st is built on the Higgins' collective years of manufacturing leadership and consulting in the medical device and sports industries. The first product was the FS6 Performance Foot Sleeve, using our patented Compression Zone Technology to lift and stretch the plantar fascia and target Plantar Fasciitis symptoms. 

In 2018, we debuted our first sock -- the FS4 Plantar Fasciitis Sock -- and grew it into a line of Socks with Purpose that target specific conditions, helping customers overcome bunions, Achilles tendonitis, circulation, diabetes, among others. 

While HQ is located in the Higgins' hometown of Hickory, N.C., the OS1st "family" extends all over the country with over 2,000 independent retailers and in 22 countries. 

    Why you feel better in our products

    All OS1st products are made with premium materials on top-of-the-line, precision knitting machines that allow for advanced textile engineering.

    Compression Zone Technology®

    We apply targeted zones of compression from moderate to firm within a sleeve or sock to target specific conditions like Plantar Fasciitis, runner's knee, tennis elbow and more.

    K-Zone® Technology 

    KZT® uses hypoallergenic gel stabilizer systems with high resistance fabrication zones to provide the benefits of kinesiology taping treatment without the inconvenience of its temporary and binding nature.

    Skin Thin® Technology

    The Skin Thin® construction is applied to socks and calf sleeves for an unmatched cooling experience. The ultra-thin panels are paired with uniquely positioned lift-bars that maximize air-flow next to the skin for a cooling sensation.
