From Yume Tenbo, these are thick-soled sock-fit long boots. I purchased them, but they didn't fit, so I'm selling them. I usually wear shoes in the 24.0-24.5cm range, but these felt a bit large. Information from the website below: "Boots you can wear like socks" Sock-fit knee-high boots ◎ 【Design】 These super-stretch sock-style boots fit your feet perfectly. The slightly thick sole adds volume, making your ankles look slender and your legs appear longer ◎ 【Heel/Sole】 A 6cm thick sole with excellent volume. There's also a 2cm height in the front, so the actual height difference is small, providing excellent stability and peace of mind ◎ The sole has unevenness and a good rubber feel, making it non-slip. 【DETAIL】 You put them on by widening the opening like a sock, and they fit your feet snugly, resulting in a sleek silhouette ◎ Perfect for everyday wear, as well as for gyaru, "jirei" (morally ambiguous), subculture, and "oshi-katsu" (supporting your favorite idol/character) to live events, they suit a wide range of styles ◎ Available in 6 sizes from 22.5cm-25.0cm. I tried them on with a stocking on the left foot only, so please refrain from purchasing if you are sensitive to this.
