A side zipper makes for quick on-and-off, a composite toe protects without steel's weight, and the sealed SCUBALINER™ membrane keeps feet dry.
Lace Once, Zip Every Day
The zipper is the point of this boot. You set the lace tension once to your foot, then get in and out with the zip — no working the laces loose at the end of a shift and re-tightening them the next morning.

Frequently Asked Questions
What's the point of the side zipper?
You set your lace fit once, then use the zipper to get in and out — no re-lacing at the start and end of every shift. It's a real time-saver if you take boots off for breaks, prayer rooms, or clean areas.
Is this boot metal-detector safe?
No. The composite toe and non-metallic shank keep steel out of the toe and the sole, but the side zipper is metal. If you need footwear that clears a metal-detector access point, this isn't the boot — look at Carolina's fully non-metallic lace-up composite styles instead.
Why choose a composite toe over steel?
It's lighter and doesn't conduct cold or heat into the toe box, while meeting the same ASTM F2413 I/C impact and compression standard as steel.
How does cement construction affect the boot?
The outsole is bonded directly to the upper rather than stitched through a welt, which keeps the Subframe light and flexible from the first day, with no break-in underfoot.
