This is the newest boot by 5.11 Tactical for Firefighters and EMS professionals. This model of the boot has a Composite Safety Toe which is ASTM F2413-05 M1/75 C/75 EH PR rated. The Company boot has a slip-on upper with heavy duty elastic and full grain leather which gives it a highly polishable toe. The outstanding feature for this 2.0 boot is the Quick Call Collar, a perforated neoprene bootie for fantastic comfort and fit. The sturdy stay-flat pull tabs add to the ease of donning and doffing the boot, and there's a hidden pocket on the boot for a key or other item. These boots have 5.11's Shock Mitigation System which makes them very comfortable for all-day wear. There's an anti-bacterial lining (great if you're making EMS calls), non-metallic construction, a composite shank, and oil/slip resistant outsole.
