Product Info for 5.11 Tactical Company 3.0 Carbon Tac Safety Toe Boot - Mens

Based on the light and flexible 5.11 Carbon Tac Safety Toe (CST) model of combat boots, the 3.0 version incorporates a host of safety features that increase durability and comfort without sacrificing safety or performance. CST provides lightweight and superior impact protection, and is approximately 20% thinner and lighter than ordinary composite toe boots, while still offering the same level of protection. The leather and nylon upper features a full-grain, waterproof, breathable cowhide leather and a DWR-treated finish. Internally, the 5.11 Tactical boot is constructed with a nylon collar at the mouth that allows for easy on and off, while a high-traction outsole with climbing lugs ensures that you will be able to move with ease no matter the footing. No matter what your footwear needs may be, you will be ready to take on your next challenge in the 5.11 Tactical 3.0 CST Boot.image
