The Mack Octane Zip 2.0 Work Boot is built for American workers who demand long-lasting comfort, rugged durability, and fast on/off convenience. Engineered for industrial environments ranging from light-duty to extreme-duty, this boot combines a lightweight composite safety toe with a heavy-duty full-grain leather upper, a dependable side-zip closure, and a heat-resistant, oil-resistant, slip-resistant outsole designed to keep you protected on the toughest job sites. The Tech-Lite Comfort Build delivers a high-performance multi-layer cushioning system that includes a 3D molded anatomical insole for exceptional support underfoot. A high-rebound polyurethane midsole absorbs shock and provides stability through long shifts on concrete, metal grading, or uneven terrain. For durability, the boot features a water-resistant all-leather upper, YKK side-zip protection, and a Desma injected midsole that eliminates glue failure and dramatically increases lifespan. Reinforced bump and scuff caps add extra abrasion protection where it counts. Function meets versatility with a 7-eyelet lacing system for adjustable fit, reflective details for low-light visibility, and a ladder-heel design engineered for climbing ladders, equipment, and steep surfaces. Inside the midsole, a lightweight flexible puncture-resistant composite plate provides underfoot protection without adding unnecessary weight. The Nitrile rubber outsole delivers slip resistance and fuel-oil resistance and is heat-rated to 572°F for high-temperature environments. Electrical Hazard (EH) protection meets OSHA expectations for general industrial workplaces, construction sites, utilities, maintenance, oil & gas, and emergency environments. Designed for workers who demand performance, the Mack Octane Zip 2.0 brings together composite-toe protection, dependable durability, and all-day comfortwithout unnecessary weight.
