Thank you for viewing! (^_^) Please also check my profile, if you don't mind. *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ I knitted these for myself because I get cold easily, and 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 stretch. 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 superfine yarn, using two strands together. As requested, I knitted the heel deeper and made them wider. ★ 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. I've knitted them with extra room so you can wear them over socks. They're 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, uneven stitches, etc., so please consider this before purchasing if you are sensitive to such things. Ankle length... Foot covers Type of socks...
