These are 15cm snow boots! They were only used once on a snow trip. The grip on the soles is excellent, so I didn't fall even when I went to a snowy region! They are also fluffy and warm inside, and the toe area is made of rubber, so they were a lifesaver as water didn't seep in even after playing for a while! Waterproof design children's snow boots, warm with fleece lining. - Color: Gray - Material: Synthetic fiber/rubber - Size: Children's - Features: Waterproof design - Design: Fleece lining Thank you for looking.
