Heel discomfort can make even simple movement feel harder than it should. The Plantar Fasciitis Socks are engineered with intentional compression zones mapped to support the arch and help reduce the sensations commonly associated with plantar fasciitis—especially during the first few steps of the day or long periods of standing.
This design is personal to us. OS1st began when our founder searched for a way to help his wife move with more comfort as she navigated plantar fasciitis. That pursuit led to the FS6® Foot Sleeve and eventually to the first-ever plantar fasciitis sock support built into something you can wear every day.
Wash gentle on cold. Tumble dry on low heat. No bleach or fabric softener.
