PRODUCT DETAILS Combining the cool of a Chelsea boot with the waterproofness of a Wellington boot, these will add attitude to your wet-weather style. Crafted in natural rubber, with stretchy side panels and grosgrain pull tabs so they're easy to pull on. And, unlike standard hard-bottomed rain boots, they feature our WonderWelly™ midsoles for amazing ergonomic comfort. We've contoured the insole to work with your natural alignment, filled the heel with impact-absorbing cushioning, and put springy high-rebound ridges at the forefoot to propel you forward with each step. Light, supportive, versatile (they're smarter than traditional rain boots) ? you'll wear yours non-stop.Upper Material : Natural Rubber Mix Lining Material : Polyester (upper), antibacterial mesh footbed Fastening : Pull-On Outsole : Slip-Resistant Rubber Technology : Wonderwelly
