Where your mission takes you shapes the tracks you leave behind. The Speed 3.0 8" Shield Boot is evidence that you're always locked in on the task at hand. Aside from appreciating the superior comfort and stability, you'll be glad to be protected from the elements and heavy, unforgiving objects. That's because the speed 3.0 Shield features 5.11's® SlipStream waterproof lining and our new Carbon-Tac Safety Toe. The Carbon-Tac Safety Toe is about 20% thinner and about 30% lighter than a standard composite toe cap, yet it provides the same level of ASTM 2413-11 impact and compression protection without the bulk or weight. This boot is also built with a puncture-resistant board for unparalleled protection, whether you're scaling a fence or facing a would-be-combatant. A low-friction odor-control lining inhibits the growth of odor-causing bacteria, and Ortholite® insoles enhance your comfort. And the slip-resistant tread helps keep you on your feet.
