Size/Fit Summary: True to size, Regular fit. Sizing suitable for 5-11 year olds (size 13-5). Big kids can explore the outdoors whatever the weather in our limited-edition Hunter X Disney Mickey Mouse Rain Boots. Made from natural, vegan rubber, these blue waterproof boots have an anti-slip sole and reflective patches on the back of the boot for additional visibility. Each pair is finished with an exclusive illustrative print of Mickey Mouse. We recommend that all Hunter boots be worn with socks to protect the wearer's skin from contact with rubber.
