Lowa Size 8.5 Renegade GTX Mid Hiking Boots • Nubuck leather upper • Polyurethane midsole • Vibram rubber outsole • Waterproof, breathable GORE-TEX linings help protect your feet from the elements I did a cursory washing of these boots. It’s possible that a deeper cleaning will remove more of the markings. These are great boots, nothing lacking in the structure of them but I realized after two hikes, I decided to size up. Minimal wear on the soles.
