OS1st Orthotic Sock

The OS1st Orthotic Sock is a barrier layer between your foot and your arch support — silicone grip pads keep the orthotic from shifting, a smooth interior reduces direct skin contact, and silver anti-microbial treatment helps fight odour through the day.

Frequently Asked Questions

Does this work with custom orthotics? Yes. It's compatible with most standard and custom arch supports that sit loose inside the shoe.

Will it work in sandals? Yes, in any sandal that accommodates a removable insole.

Are they sold as a pair? Yes, one pair per box.

Will the silicone pads damage my orthotic? No. The pads grip without adhesives and lift off cleanly when you remove the sock at the end of the day.
