Frequently Asked Questions
Are these the same as a calf sleeve plus a regular sock? Functionally similar, but the FS4+ knits it all into one piece — no slipping, no overlap, no double layer where the sleeve meets the sock.
How much compression do they apply? Graduated — firmer at the ankle and arch, easing up as it travels toward the top of the calf. It's noticeable but comfortable for all-day wear.
Are they sold as a pair? Yes, one pair per box.
Will they fit inside work boots or dress shoes? Yes. The thin, flexible profile is designed to layer inside most closed footwear, including work boots and dress shoes.
