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 listing them because I want those who have cold feet to try them. Please give them a try! (ㆁᴗㆁ✿) *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ✿ Approximately 24 cm when laid flat. Since they are made of yarn, there is some stretch. For those who prefer a loose fit, or a snug fit, please consider your own foot size and choose accordingly. o(^▽^)o *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ★ These are knitted with two strands: worsted weight wool and fine acrylic yarn. ★ Soft elastic is knitted into the ankle area, making them easy to stretch and put on/take off. Even if you repeatedly put them on and take them off, the ankle part won't stretch out and become useless. 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! Also, they are thin enough to wear slippers over them. ✾ No non-slip material is attached. ✾ These are handmade items by an amateur. There may be distortions and uneven stitches, so please consider this before purchasing. Ankle length... Foot covers Type of socks... Room socks Pattern/Design... Almost plain
