Size/Fit Summary: True to size, Regular fit. Sizing suitable for 5-11 year olds (size 12-4). Our 100% waterproof Glacial Camo Rain Boots are handcrafted from natural, vegan rubber with a matte finish and fitted with a polyester lining for comfort. This blue pull-on style has an anti-slip tread for grip on slippery surfaces and reflective patches for increased visibility. We recommend that all Hunter boots be worn with socks to protect the wearer's skin from contact with rubber. All Hunter Boot Socks are specially designed for use with our kids boot range and feature a fold over top to cover the rubber and nylon boot edge, preventing any rubbing associated with wear.
