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 24-25 cm. 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 a combination of wool and acrylic medium-weight yarn + fine acrylic yarn, using two strands. ★ Soft elastic is knitted into the ankle area, making them stretchy and 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 become damaged easily. 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 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...
