Introducing the Mammut Comfort Tour Mid GTX! Mammut took their best seller, the Mercury, and equipped it with Comfort Surround. That means it is even softer, more comfortable, slightly wider in the forefoot, has a lower heel drop and offers increased breathability thanks to the GORE-TEX SURROUND technology. This comfortable footwear is made from high-quality Nubuck leather and Soft Shell fabric. The proven gripex Comfort sole with built-in Sonar technology ensures grip and comfort on almost all surfaces. The patented Rolling Concept and an arch support are also integrated into the IP EVA wedge, which provides excellent cushioning. A lightweight liquid rubber protects the toe cap.
