Please note: Hunter Kids lists the UK size on all footwear. For example, if you order a US 10 Toddler the size printed on footwear and packaging will be a size 9. You'll always remember your little one's first puddle jumping experience! Make sure they're styled and ready with the Hunter® Original Kids' First Classic rain boot. The Hunter Kids First Classic is a specialized welly, designed for growing feet. A flatter sole and rounder foot ensure this rain boot style is easier to walk in. A wider upper leg offers freedom of movement, as well as making the putting-on and taking-off process easier. This Hunter boot is Handcrafted from 28 parts, for an assured quality performance and comfortable fit. Made of vulcanized natural rubber. Certified Vegan. Comfort cushioned footbed. Woven nylon lining. Calendered natural rubber outsole for sure-footing. The brand advises that a white wax film may appear on the surface of the rubber boots and that it can be wiped off with a damp cloth. This "blooming" effect is not a defect. Blooming is caused when the boots are exposed to extreme temperatures or temperature swings and the wax helps prevent the rubber from weathering.
