The Carolina Line Builder is a men's work boot designed to provide protection and durability in harsh working conditions. The Carolina Line Builder features a waterproof aluminum safety toe cap and a polyurethane internal metguard to protect the feet from impact and compression hazards. The waterproof SCUBALINER™ ensures that the feet stay dry and comfortable, even in wet conditions. Key Features of the Carolina CA8533 Aluminum Safety Toe Cap — A metal cap, lighter than steel; meets ASTM F2413 I-75/C-75 for impact and compression. Polyurethane Internal Met Guard — Non-metallic metatarsal protection meeting ASTM F2413 Class Mt75, built beneath the upper for a lower profile. Waterproof SCUBALINER™ — Carolina's sealed proprietary waterproof lining system. Dark Brown Crazy Horse Leather Upper — Rugged leather that distresses handsomely with wear. Pull-On Wellington — No laces to snag, untie, or catch. Mesh Lining & Removable AG7™ Polyurethane Footbed — Breathable, with enhanced arch support. PC2™ Internal Polyurethane Midsole — Cradles the footbed for anatomical support underfoot. Electrical Hazard Rated — Tested to withstand up to 18,000 volts at 60Hz for one minute without leakage. Non-Metallic Shank — A composite shank that saves weight and flexes with the foot. Welt Construction & Goodyear Heavy-Duty 150+ Abrasion Outsole — Rebuildable, with a high-abrasion slip-resisting tread. Protection Where a Toe Cap Ends A safety toe covers the toes and nothing else. The internal met guard extends Mt75 protection back across the metatarsal bones — the long bones on top of the foot that take the hit when something heavy rolls or drops onto the instep. Building it internally keeps the profile lower than a strap-on external guard. Why an Aluminum Toe Aluminum meets the same I-75/C-75 thresholds as steel while weighing noticeably less, and it's thinner than a composite cap of equal rating — so it preserves toe-box room.
