Warm and Dry in the Cold
Thinsulate™ microfibers trap air without absorbing water, so 800 grams keeps working even when the leather is soaked — and the sealed SCUBALINER™ keeps the water outside in the first place.
Heavy-Duty Support
A triple-rib steel shank and welt construction give the CA9028 a stable, rebuildable platform, and the one-piece rubber lug outsole grips uneven, frozen ground.
Why Choose the CA9028?
A serious cold-weather work boot — heavily insulated, waterproof, and built on a welt platform you can resole.

Frequently Asked Questions
Is 800g the right amount of insulation for me?
800g is built for standing still in genuinely hard cold — outdoor utility, winter yard work, cold storage. If your work keeps you moving through the day, the non-insulated CA8028 on the same platform is the better match, since insulation ratings assume your own movement supplies part of the heat.
Can it be resoled?
Yes. Welt construction stitches the outsole to the upper, so the lug sole can be replaced when the tread wears down — worth having on a boot this heavily built.
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.
Does the CA9028 have a safety toe?
It is a soft-toe boot with no ASTM F2413 toe rating; it carries an EH electrical hazard rating and the rubber lug outsole is oil- and slip-resisting.
How does the 28 Series CA9028 fit?
It runs true to size — order the size you wear in athletic shoes, and choose Wide if you normally need an EE width. With 800g of insulation it runs warm, so wear the sock weight you plan to work in when you try it on; the AG7 footbed is removable.
How do I care for the CA9028?
Knock off dirt, wipe the leather clean, let the boot dry away from direct heat, and condition the leather every few months. Welt construction means a cobbler can resole it when the lug outsole wears.
