Lightweight, Waterproof Protection
The composite toe delivers non-metallic impact and compression protection, the sealed SCUBALINER™ membrane keeps water out, and a breathable mesh lining lets moisture escape.
A Clean Black Boot, Light on the Foot
Pebble-grain black leather keeps the Circuit presentable where a tan hiker wouldn't be, and the composite toe and non-metallic shank keep the whole structure of the boot free of steel — lighter underfoot, and warmer at the toe in winter.
Why Choose the CA3537?
A clean black waterproof composite-toe hiker, light enough for all-day wear and free of metal throughout.

Frequently Asked Questions
Why choose a composite toe over steel?
Both meet the same ASTM F2413 impact and compression thresholds. Composite transfers far less cold and weighs less across a long day; steel is thinner and preserves slightly more toe-box room at the same size.
How long does the waterproofing last?
The SCUBALINER™ is a sealed membrane rather than a surface coating, so it doesn't wash off. Conditioning the leather and keeping the seams clean is what keeps it working over the life of the boot.
