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✿) *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ✿ Flat measurement is about 24-24.5 cm. Since it's yarn, there is some stretch. For those who like a loose fit, and those who like a snug fit, please consider your own foot size and choose accordingly o(^▽^)o *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ★ These are knitted with two strands: acrylic bulky yarn + superfine yarn. It's a mohair-like yarn. ※ In the photos, there are some parts that look navy blue, but they are gray. The color of the toe area on the left side is the closest to the actual color. ★ Soft elastic is knitted into the ankle area, so it stretches well and is easy to put on and take off. Even if you repeatedly put them on and take them off, 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 before purchasing. Ankle-length... Foot covers Type of socks... Room socks Pattern/Design... Partial border
