Our men's 8" waterproof insulated steel toe internal metguard logger combines protection and all-condition comfort.
It's equipped with 600 grams of Thinsulate™ insulation to help keep out the cold, and our waterproof SCUBALINER™ to help keep your feet dry all day long. The Pillow Cushion™ footbed provides underfoot support, and the oil- and slip-resisting outsole provides excellent traction.

Serious Protection Up Top
Beyond the steel toe, an internal met guard shields the metatarsal bones from falling and rolling objects — an important safeguard for logging, foundry-adjacent, and heavy-material work — while staying more comfortable than a bulky external guard.
All-Weather Comfort
The SCUBALINER™ membrane seals out water and 600g of Thinsulate™ traps warmth, so the CA7821 stays dry and warm through cold, wet conditions.
Why Choose the CA7821?
It stacks steel-toe, internal-met-guard, waterproof, and insulated protection onto a rebuildable welt logger — a lot of defense in one all-condition boot.

Frequently Asked Questions
What sizes and widths is the CA7821 available in?
We carry it in Medium, Wide, and Extra Wide, in sizes 7 through 15, with half sizes through 11½.
What does the internal met guard do, and what is Mt75?
The met guard shields the metatarsal bones — the long bones across the top of the foot, which a toe cap doesn't cover — from falling and rolling objects. Mt75 is the ASTM F2413 rating for metatarsal protection at the 75-foot-pound impact level, the same energy level as an I-75 toe. Building it internally keeps the profile lower than a strap-on external guard.
Do I actually need a met guard?
It depends on what's above your feet. Met guards are specified where heavy objects can drop or roll onto the instep — logging, foundries, steel handling, heavy material yards. If your hazard assessment doesn't call for Mt-rated footwear, a plain steel toe is lighter and more flexible. Your site safety officer sets that requirement, not the boot.
Can it be resoled?
Yes. Welt construction stitches the outsole on rather than cementing it, so the lug sole can be replaced when it wears through.
