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 wanted people who have cold feet to try them, so I'm selling them. Please give them a try! (ㆁᴗㆁ✿) *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ✿ Approximately 23.5 cm. Since they are made of yarn, there is some give. If you prefer a loose fit, or a snug fit, please consider your own foot size. o(^▽^)o *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ★ These are knitted with 100% wool bulky yarn + acrylic fine yarn, using two strands. As requested, I've knitted the heels deeper. ★ Soft elastic is knitted into the ankle area, making them easy to put on and take off. Even if you put them on and take them off repeatedly, the ankle part won't stretch out and get ruined easily. I've knitted them 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 thick enough to wear slippers over them. ✾ No 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 concerned. Ankle length... Foot covers Type of socks... Room socks Pattern/Design... Bordered
