Lightweight, Convenient, and Dry
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 — in a taller 8" build with added coverage.
Lace Once, Zip Every Day
The zipper matters most at this height. An 8" boot takes the longest to lace and unlace, so setting the fit once and using the zip for daily on-and-off saves real time across a week.
Why Choose the CA5552?

Frequently Asked Questions
What's the difference between the CA5552 and CA5550?
Height only — the CA5552 is the 8" version with more ankle and lower-leg coverage; the CA5550 is the 6" cut. Same waterproof, side-zip, composite-toe platform.
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.
What's the point of the side zipper on a work boot?
You lace it to your fit once, then zip in and out — especially handy on an 8" boot, where full re-lacing takes the longest.
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.
