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. Here in a super-cozy multi-wear design that can be worn up as a tall boot, for more protection in heavy rain/snow, or rolled down in milder weather. These boast a waterproof lower, crafted from thicker rubber with a stylish 'tumbled' texture, teamed with a cushiony non-wicking stretch nylon shaft. All lined in soft fluffy duvet-warm faux-fleece to keep you toasty on cold walks (and that looks fab when pulled down). With a thicker, deeper, grippier tread giving 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: The stretch faux-fleece lining is 50% PET polyester recycled from plastic bottle waste.Fully waterproof vulcanized natural rubber-mix lower Thick warm stretch nylon shaft (water-resistant when rolled up)Deep angular tread pattern & lugs give Level 3 grip (suited to heavy trails/off-trail/thick mud/snow) Removeable cushioned EVA footbeds Smart utility looks also work for the city
