Reebok made these tan combat boots specifically to military personnel usage and needs. Little or no break-in period required. Ultra Light & Comfortable. The outsole is injected with EVA (Ethylene-Vinyl Acetate): durable and light rubber foam. The midsole contains a Lenzi ® plate which is a lighter substitute to the traditional steel plate, while still protecting your feet from punctures. In fact, nothing in this tactical boot is metallic. They’re airport friendly boots. All of the key elements that come in contact with your foot pads are shock-absorbent: the insert, upper sole, and outsole. The midsole’s Lenzi ® plate provides lateral stability over mountainous terrain and repels any extra shock due to impact on the ground. The outsole has an excellent anti-vibration capacity. This means you feel less impact on your feet and legs. Durable & Puncture Resistant. • Hard shell around the toes • 550 paracord boot laces • Lenzi® puncture protection plate – meets or exceeds the requirements of the ASTM F2413 Safety Standards. • 1000 Denier nylon panels • Flexible EVA rubber outsole. Superior Traction. The EVA rubber outsole also protects you against slipping on wet or oily surfaces. This technology is water-repellent with good anti-skid characteristics. Include that with the traction design and lugs, and you have a combo of protection against slipping on rocks and sand. Keeps Out Moisture. • The inner lining has an AEGIS ShieldTM, wicking moisture and protecting your feet from bacteria, fungus, and other microorganisms. • Air Vents – The removable insert has air vents under the arch and the balls of the feet where heat is generated the most. The insert also wicks away moisture. • Side Ports – Any hot air, excess moisture, or water due to water exposure is released from the medial side ports, located near the air vents of the removable insert, and under a panel of water-resistant 1000D nylon.
