Thank you for viewing! (^_^) Please also check my profile, if you don't mind. *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ I knitted these for myself because I get cold easily, but I'm selling them because I want people who have cold feet to try them out. Please give them a try! (ㆁᴗㆁ✿) *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ✿ Flat measurement is about 24.5 cm. Since it's made of yarn, there's some stretch. For those who like a loose fit, and those who like a snug fit, please consider your own foot size and choose accordingly! o(^▽^)o *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ★ These are very warm, made with thick 100% wool + extra-fine acrylic yarn, a double thread, and an extra-thick type. The ankle part is also knitted a little longer, so they are very warm. Recommended especially for those with cold feet! They are knitted with extra room so you can wear them over socks. They are not like rigid room shoes, but have a fit that allows your toes to move freely! ★ No special non-slip material is attached. ❀ These are handmade items by an amateur. There may be distortions, uneven stitches, etc., so please consider before purchasing if you are sensitive to such things. Ankle length... Foot covers Type of socks... Room socks Pattern/Design...
