When the going gets tough grab the ATB (Advanced Terrain Boot) version of our WonderWelly – robust high-performance rain boots with the sneaker-like comfort of the original. These boast fully waterproof uppers – in a new design, with thicker rubber and a 'tumbled' texture – to keep you dry, whether you're wading a stream or facing a storm. Lined in soft super-thick cushiony nylon for an enhanced fit and warmth on cold walks. With a thicker, deeper, grippier tread giving you extra stability off-path, on rough loose ground, and in the wettest heaviest mud. While retaining all the WonderWelly™ comfort features: contoured cushy footbeds that work with your natural alignment; impact-absorbing 'honeycomb' heel cushioning; and flexible outsoles, with springy ridges under the forefoot to help you 'push off'. Essential. Unstoppable. Likely to be a hit with anyone regularly out in challenging conditions (dog walkers, nature lovers, farmers, gardeners, horsey types, country vets, coastal strollers, off-trail enthusiasts...). Note: Fastening hardware is 100% recycled zinc. Fully waterproof vulcanized construction (like every WonderWelly) Heel kick for easy removal Adjustable gusset (with sturdy webbing strap & hook fastening) for optimum security/fit Deep angular tread pattern & lugs give Level 3 grip (suited to heavy trails/off-trail/thick mud/snow) Removeable cushioned EVA footbeds (swap with WonderWelly Luxe Shearling Insoles for extra coziness) Classic utility looks also work for the city
