The LOWA Explorer GTX Mid is built around the all new Vibram Rock Trac Evo sole, with a unique tread pattern for traction on rough terrain. The lighweight midsole is made of DynaPU, delivering the highest level of cushioning ever in a Trekking boot; perfect for keeping you going mile after mile. Cement construction gives a precise fit, and allows the boot to be resoled in the future. The highly breathable suede upper uses termo-embossing to add strength without adding weight. The boot has a lightweight, tape lacing system for an accurate, precise fit, especially around the heel. A TPU toe cap adds protection, and the Gore-Tex Performance waterproof membrane is there to provide optimum comfort in all conditions.
