How it started 

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.

    Compression Zone Technology®

    Starting with the FS6, we’ve patented a way to target specific areas with different levels of pressure. Instead of a tube of graduated compression, our products have the right level of compression just where you need it.

    Socks with Purpose®

    After the success of the FS6 Performance Foot Sleeve we turned it into the first-ever Plantar Fasciitis sock. Since then we’ve continued to build our sock line with solutions for every runner’s needs - performance, lifestyle, and pain relief.
