The Explorer II GTX Mid comes equipped with all of the features you'd expect from a lightweight Trekking boot, allowing you to keep going in all day complete comfort. The brand new DynaPU+ midsole provides supreme levels of comfort and cushioning in the Explorer II GTX Mid. The DynaPU+ allows for greater rebound properties, providing a spring in your step and helping to save energy at the same time. The lightweight suede leather & fabric upper is thermo-embossed to add strength, all while keeping weight down, while the Gore-Tex membrane keeps all the weather out and works with the leather to create a highly breathable boot. A Vibram® Rock Trac® Evo sole utilises the Vibram® Megagrip rubber compound to provide all of the grip you need, while the TPU toe and heel cap adds extra protection. Due to its bonded construction, the Explorer II can be resoled to extend the life of the boots.
