The Kids First Classic Nebula Rain Boot is perfect for puddle splashing and mud playing. Handcrafted from natural rubber, the flat sole and rounded toe give little feet room to move and the updated 100% recycled polyester lining ensures complete comfort for every adventure no matter how big. These boots are fully waterproof and feature a specially-developed tread to reduce slipping. We recommend that all Hunter boots be worn with socks to protect the wearer's skin from contact with rubber.
