While we do not offer kid's sizing, FLAT SOCKS are 100% trim-to-fit. You can easily purchase a Small or Large pair and trim them down to fit any shoe size! Hint: Large FLAT SOCKS are wider and could provide more coverage.
Trimming Directions
If possible, remove shoe’s insole and use as a guide for trimming your FLAT SOCKS. Replace shoe insole when finished. If your shoe’s insole is glued in or difficult to remove, use trim guides stamped into the underside of FLAT SOCKS to trim to the right size.
