Easy-to-attach and detach dial-style trekking shoes and walking shoes for kids. - Color: Blue/Gray - Design: Dial-style - Material: Synthetic fiber/Mesh - Size: 23.0cm Thank you for viewing. I bought these for my child's mountain climbing, but they didn't fit, so they've never been used. My child, who usually wears 23.0cm shoes, found these to be a bit small, so please consider this when making your decision. When climbing mountains, you'll wear thick socks, so please take that into consideration as well.
