Built for EMS and Duty Use
The ASTM F1671-24 bloodborne pathogen certification is a genuine differentiator for this boot — it's built to hold up to the demands of EMS and duty work, not just general tactical training.
Why Choose the Danner FullBore 4.5" 20511?
If you want a lightweight, genuinely waterproof duty boot with real EMS-grade certification, this is it. Danner Dry waterproofing, the Vibram Fuga/SPE platform, and ASTM F1671 protection come together in a boot built for off-duty training and demanding field use alike.
