The length is 400mm, but it can be made a little shorter if you cinch it. The color is Olive, and the size is L, but I think 25.0cm and thick socks would be just right. I used to wear them too, but I waited 1-2 years longer than my colleagues. When I finally wore them, I thought, "Why did I wait so long?" (lol) Anyway, I was surprised at how light and warm they were. There are also some disadvantages that only a user would know. First of all, due to the material of the product, it's sensitive to heat and sharp objects. My colleagues' boots were deformed because they dried them in front of the stove (lol). I always took out the inner lining and dried them separately, but that was enough to dry them completely. Sharp objects are strictly prohibited. Also, although it's not mentioned in the handling instructions, I think you need to be very careful when driving a car. This is because the shape of the BOOTS restricts the movement of the ankles, so you may feel stress when braking. You can do it if you force it, but safety is the most important thing. When shipping, the boots will be taken out of the box and shipped in a 100-size cardboard box. Everything in the photos is included. Thank you for looking. Thank you.
