These Rocky Alpha Force boots are made with the Rocky Waterproof system. This system lets air flow in, but keeps water out. These black leather boots have 400 grams of ThinsulateTM Ultra insulation. With dry and warm feet, you won't be distracted from the job at hand. To further assist with your duties, you need boots that can keep up with you. The Alpha Force has a special oil-resistant and slip-resistant RigiTracTM molded EVA/rubber outsole. These soles really grip the terrain to help you maintain your footing. Rocky designed these shoes with thought as to what your job entails. Inside, a non-metallic stabilizer provides support for your feet, but it won't set off metal detectors if your job requires that you pass through detectors frequently. If you're on your feet for much of the day, you also want your boots to be comfortable. You want the Rocky Air-PortTM footbed. This footbed is a high-performance, cushioning and comfortable footbed that circulates air with every step. It's molded from durable PU that won't break down or lose its shape. In addition to performance, these eight-inch duty boots also have the styling you want. They are made with full-grain leather and 900-denier combination nylon. These materials resist abrasions. Alpha Force is a completely black boot with black laces and a black side zipper.
