I've used these about twice for room-temperature Pilates, but they have some pilling and fuzzing because I washed and dried them at home. They're still in usable condition, so how about it if you want to try them out, or need a spare pair? Please purchase only if you understand that these are used items. - Brand: SUKALA - Color: Gray - Design: Five-finger socks - Non-slip: Yes Thank you for looking.
