Designed for rainy-day adventures, the Sperry Toddler Chelsea Rain Boot features a waterproof one-piece molded construction and a slip-on Chelsea silhouette for easy wear. A cozy textile lining adds comfort, while the rubber outsole provides traction on wet surfaces.To enhance grip, the outsole is treated with a traction coating that may cause the sole to appear slightly marked or worn prior to first use. This is a normal part of the manufacturing process and does not affect performance or durability.
