Be ready to tackle any environment with the Reebok 6" Rapid Response RB SZ WP. This combat boot features a removable F2 dual-density polyurethane cushioned insert, which has a heel stabilizer and Shock Eliminator heel cushion to protect your feet from impact and provide complete stability. This waterproof boot is built with a smooth leather and Cordura upper and a Mountain Trail rubber bottom for maximum grip and traction. The most advanced feature of this boot is the Tailex lining, which captures moisture, then allows it to evaporate quickly once the boot is removed. This prevents the buildup of moisture in the boot, eliminating blisters and odor-causing bacteria. This lining also creates small air pockets to help maintain a pleasant climate within the boot and provide breathing room for more comfort during tactical operations.
