Frequently Asked Questions
Can I wear them barefoot inside shoes? Yes — many customers wear the FS6 directly against the foot inside running shoes or work footwear. You can also layer a sock over top.
Are they sold as a pair? Yes, two sleeves per package.
How is it different from a compression sock? A compression sock applies uniform pressure from the ankle up. The FS6 is footwear-only — six mapped zones target the arch and heel without a cuff around the calf or ankle.
Can I wear them at night? The FS6 is designed for daytime, active wear. For overnight plantar fascia routines, the DS6 night-time sleeve is the better pick.
