For demanding work, you need boots that can handle anything. The advanced Hydro-Tec® Sanitized Silver construction offers perfect protection for your feet; the Mendoza is ready for the real work in the chemical industry or agriculture. These boots pass tests in which they are fully submerged for seven hours. This means they’re waterproof inside and out. What makes them even more special is that your feet can still breathe, keeping them cool, dry, and fresh.
