Why Carbon Fiber Instead of Steel
A carbon fiber weave hits the same ASTM impact and compression thresholds as steel at lower weight, and it doesn't pull cold into the toe box on a winter site. On a boot you'll wear ten hours a day, that weight saving is the difference you feel in the muscles that lift your feet.
A Welt You Can Resole
The leather welt is stitched through the upper and insole, and the outsole is stitched to it. That seam can be cut and re-stitched, so the boot outlives its first sole — unusual at this price, and the main reason to choose a Staple Gun.
Why Choose the CA7570?
Waterproof, EH rated, safety-toe protection without the weight of steel, on a sole you can replace.

Frequently Asked Questions
Is the CA7570 true to size?
Carolina generally runs true to size — order the size you wear in sneakers, unlike Red Wing or Thorogood, which tend to run large. If you're between widths, take the wider one; feet swell over a shift.
Is a carbon composite toe as protective as steel?
Yes. Both meet the same ASTM F2413 impact (I/75) and compression (C/75) thresholds. Carbon composite is lighter and transfers less cold; steel keeps a slightly slimmer profile.
Can it be resoled?
Yes. Leather welt construction stitches the outsole to the upper rather than bonding it, so a cobbler can replace the outsole when the tread wears down.
Is it insulated?
The CA7570 is waterproof and uninsulated, which makes it a comfortable three-season boot. If you need winter warmth, Carolina builds insulated models rated by gram weight.
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.
