Our go-to puddle jumper is back and better than ever with a more streamlined design; the Sorel Children's Rainbou Rainboot is built from vulcanized rubber for a completely H2Oproof and seriously durable shell that stands up to rough-and-tumble play. Inside, a removable liner provides insulation on cold days, but pulls out easily to create the Great warm-weather rain boot. The result is a versatile boot thats nice all year long.
