5.11 Tactical Company 3.0 CST Boot (12421)
Slip 'em on. Step it up. Stay protected.
The 5.11 Company 3.0 CST Boot is what happens when protection, comfort, and convenience show up for duty together. Designed for station life but built to perform when the pressure’s on, these ultra-light safety toe boots are made for firefighters who need gear that keeps up—on and off the rig.
Let’s start with the Carbon-Tac® Safety Toe — it’s ASTM F2413-17 M I/75 C/75 EH + PR certified, just like a traditional composite toe, but 30% lighter and 20% thinner. Translation: legit protection without the bulk. Add a puncture-resistant Wellmax® board, and you’re ready for anything underfoot—glass, nails, rebar, you name it.
The Force Foam™ PU cushioning keeps foot fatigue off the table during those long shifts, and the new Ortholite® Achilles padding gives you extra comfort where it counts. Need to move fast? You’ll love how these slip-on, slip-off with zero fuss thanks to a redesigned nylon collar and heel pull.
Whether you’re headed to the truck bay or walking post-incident mop-up, the water-resistant leather upper and slip/oil-resistant outsole grip and go—even on the sketchiest surfaces.
