All kids, big and small, love to explore- no matter what the weather or situation. Less than half the weight of conventional rubber boots and with an upper that covers the entire lower leg, our Explorer boots are made with waterproof materials and the sewing seams are sealed. Patent-pending Explorer boots are adjustable at the ankle and knee so they stay on and prevent splashed water from entering at the top. The Explorer boot collection is sold in seven sizes to fit kids aged approximately 18 months to 10 years, keeping kids big and small playing outside for hours.
