Size/Fit Summary: True to size, Regular fit. Sizing suitable for 18 months to 8 years old (size 5-2). If they are in-between sizes, it is recommended to size up. With a bright seasonal blue design, this kids boot is perfect for puddle splashing. Handcrafted from natural rubber, a flat sole and rounded toe gives little feet room to move and the soft cotton lining ensures complete comfort for every adventure. 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.
