Roomy, Lightweight Protection
A broad carbon composite toe protects without steel's weight while giving your toes extra room, and the sealed SCUBALINER™ membrane keeps feet dry.
What the Extra Two Inches Buy You
An 8" shaft supports the ankle laterally and keeps mud, gravel, and debris out. It costs a little flexibility and a little heat. On broken ground or in a trench, the taller shaft earns its keep.
All-Day Comfort
A removable AG8™ dual-density footbed cushions each step for enduring support, and it lifts out if you'd rather use your own orthotic.
Why Choose the CA5543?
A roomy, waterproof, carbon composite-toe boot for workers who want a broader toe and all-day comfort, with ankle coverage.

Frequently Asked Questions
What does “broad toe” mean here?
A wider last through the toe box, not a wider overall width. You order your usual width; the extra room sits across the forefoot.
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.
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.
How does cement construction affect the boot?
The outsole is bonded directly to the upper rather than stitched through a welt, which keeps the boot light and flexible from the first day, with no break-in underfoot.
Is it insulated?
The CA5543 is uninsulated, which makes it comfortable across three seasons. For cold work, the CA5547 carries 440g on the same platform.
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.
