5.11 Tactical A.T.A.C.® 2.0 6" Shield Boot (12443)

Low profile, full protection. Built for duty, not downtime.

The 5.11 A.T.A.C.® 2.0 6" Shield Boot is where lightweight comfort meets full-on safety. Designed for high-risk, high-mobility jobs, this shorter profile doesn’t skimp on serious protection. Whether you're working EMS, fire-rescue, or law enforcement, this boot keeps you moving fast while keeping your feet covered from top to sole.

Built with a SlipStream™ waterproof/bloodborne pathogen-resistant membrane, this boot is all about keeping the bad stuff out. Add in a CSA/ASTM-certified Carbon-Tac® safety toe, puncture-resistant board, and you’ve got protection that’s ready to face hazardous environments without hesitation.

Comfort’s not an afterthought either. The dual-density Ortholite® footbed, ankle foam, and Achilles flex zone are designed to fight fatigue and keep you mobile all day. The YKK® side zipper makes them easy to slip on and off, while the Agion® antimicrobial lining helps keep things fresh—no matter how hard the shift gets.

And yes, the full-grain waterproof leather toe is polishable—so even after 12 hours of chaos, you’ll still look sharp at inspection.
