OS1ST makes performance socks and foot support products designed around the mechanics of the foot. Instead of applying the same pressure everywhere, the brand uses targeted compression, anatomical shaping, and performance materials to support specific areas. The story began when founder Dave Higgins created the brand's first product, the FS6 Performance Foot Sleeve, after seeing his wife struggle with plantar fasciitis. The company began in Hickory, North Carolina, and still runs under the Higgins family. At Sole Provisions, the OS1ST collection includes compression socks, foot sleeves, bunion relief, plantar fasciitis support, wellness compression, and lightweight everyday socks, and it sits naturally beside our wider men's socks and women's socks selections.
A Brand Built Around a Personal Need
OS1ST grew out of a real problem: helping someone close to the founder find relief from foot pain. That origin still shapes the products, which focus on practical support for people who spend a lot of time on their feet. The name is pronounced "oh-ess-first," and the brand's motto is "Engineered with a purpose, for a purpose."
Compression Designed Around the Foot
The core technology is Compression Zone Technology, which applies different compression levels in targeted areas of the foot and lower leg rather than uniform pressure. The brand calls this approach Engineered Support. The idea is to give the foot support where it matters most while keeping the sock comfortable.
Targeted Support for Plantar Fasciitis
Several OS1ST styles, including the FS4 Merino Plantar Fasciitis quarter crew, are designed around plantar fasciitis support. If foot pain is a concern, you can also explore our arch support shoes, our guide to sneakers for plantar fasciitis, and shoe inserts. For persistent pain, a healthcare professional can advise what is right for you.
More Than One Kind of Foot Support
The collection covers more than plantar fasciitis. The BR4 Bunion Relief no show socks are designed with bunions in mind, the FS6 Performance Foot Sleeve offers targeted compression for the arch, and Wellness Compression over the calf styles offer graduated support for everyday wear. Browse our bunion shoes and wide width shoes for footwear with more room.
Lightweight Socks for Active Days
Styles like the Wicked Comfort quarter crew and crew socks, the Merino Wool Wicked Comfort crew, the TA4 Thin Air no show, and Nekkid Comfort are made for active days and everyday wear. They use moisture managing yarns for comfort, and they pair well with walking shoes, Hoka, and Brooks.
Compression That Fits Into Normal Footwear
OS1ST products are designed to fit under normal footwear, using precision knitting to stay thin and flexible. That means you can wear them in your usual sneakers, work shoes, or boots without needing a larger size.
Choosing the Right OS1ST Style
Before ordering, check the compression level, coverage, materials, and intended use on each product page. If you want an extra layer of support, the page also points to our Aetrex Orthotics and Powerstep collections. For a personal fitting, visit one of our Sole Provisions locations, or read more in our educational hub.
