These shoes have been designed with your trail experience in mind, featuring a waterproof membrane that effectively blocks out water while allowing moisture to escape, ensuring your feet stay dry and cool regardless of the weather conditions. Merrell has employed recycled materials in the construction of the Men's Speed Eco Waterproof Shoes, including the laces, upper, lining, EVA footbed, and rubber outsole. This makes these shoes one of the most sustainable and environmentally friendly hiking shoes offered by Merrell. The Cleansport NXT treatment provides natural odour control so you can stay fresher for longer throughout your hike. The lightweight EVA foam midsole adds day-long stability and cushioning, and the grippy outsole provides surefooted traction on a variety of terrain.Waterproof membrane seals out water and lets moisture escape77% recycled Jacquard upper100% recycled laces and webbingBellows tongue keeps out debris100% recycled breathable mesh lining100% recycled mesh footbed coverCleansport NXT treated for natural odour control50% recycled removable EVA foam footbedLightweight EVA foam midsole for stability and comfort30% recycled rubber outsoleStack Height: 31-21mmDrop: 10mmLug: 4mmWeight: 1 lbs-8oz/680g
