Carbon Composite Safety Toe Cap — A carbon fiber weave cuts toe-cap weight while meeting ASTM F2413 for impact (I/75) and compression (C/75).
-
Russet Leather Upper — Carolina's signature leather, on an 8" shaft.
-
Waterproof SCUBALINER™ — Carolina's sealed proprietary waterproof lining system.
-
Removable AG8™ PU Dual-Density Foam Footbed — Cushioning with arch support; swap it out to extend the boot's comfortable life.
-
EVA Midsole — Shock absorption underfoot.
-
Electrical Hazard Rated — Tested to withstand up to 18,000 volts at 60Hz for one minute without leakage.
-
Oil- & Slip-Resisting Rubber Outsole — Traction on slick and uneven surfaces.
Why Carbon Composite
A carbon fiber weave reaches the same ASTM impact and compression thresholds as steel using less material. The toe cap ends up lighter and slightly slimmer than standard composite, and unlike steel it doesn't pull cold into the toe box on a winter morning. On an 8" boot, where weight accumulates at the end of a shift, that matters.
What the Extra Two Inches Buy You
An 8" shaft supports the ankle laterally and keeps debris out on broken ground. It costs a little flexibility and a little heat — on uneven terrain, the taller shaft earns both back.
A Footbed You Can Replace
The AG8™ footbed lifts out. When it packs down — and every footbed eventually does — you replace it rather than the boot, or drop in your own orthotic.
Why Choose the CA7571?
Waterproof, EH rated, carbon-toe protection with real ankle support — for construction, industrial, and outdoor work.

Frequently Asked Questions
How is carbon composite different from standard composite?
Both are non-metallic and both meet the same ASTM I/C thresholds. A carbon fiber weave reaches that rating with less material, so the toe cap is lighter and slightly less bulky than a standard composite cap.
Why choose this over a steel toe?
Same protection rating, less weight, and far less cold transfer into the toe box. Steel is thinner, so it preserves marginally more room at the same size — that's the trade.
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.
Is it insulated?
The CA7571 is waterproof and uninsulated, which makes it comfortable across three seasons. For cold work, Carolina builds insulated models rated by gram weight.
Can I use my own orthotic?
Yes. The AG8™ footbed is removable, so an aftermarket orthotic drops straight in.
Does the EH rating still apply when the boots are wet?
Treat it as reduced. EH testing is performed under dry conditions; moisture, damp leather, and worn outsoles all degrade insulation. EH footwear is secondary protection — never a substitute for de-energizing a circuit or using primary PPE.
