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 24 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 two strands: acrylic worsted weight yarn + very fine yarn. It's a mohair-like yarn. ★ Soft elastic is knitted into the ankle area, so they stretch well and are 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. They are knitted with extra room so you can wear them over socks. They are not stiff like 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, uneven stitches, etc., so please consider before purchasing if you are concerned. Ankle length... Foot covers Sock type... Room socks Pattern/Design... Solid color
