The Power Shift Chukka Boot combines the rugged style of a heritage silhouette with the slip-resistance of a hard-working hospitality shoe. Designed to blend versatility and function, it's made with a premium full-grain leather that's as durable as it is refined. Our 24/7+™ comfort platform helps keep your feet cushioned all day, while a lightweight HoverSpring™ foam offers high-rebound performance. The boot is complete with a GripMax™ outsole, which utilizes our patented "wiper" technology to help enable greater surface contact with less-contaminated surfaces, providing slip resistance in the presence of wet and oily contaminants. A unique comfort system that meets the most rigorous worksite demands - 24 hours a day, 7 days a week. The Timberland PRO® 24/7 comfort suspension system technology is designed to help reduce foot fatigue, support the arch and cushion every step with an Ortholite® PU footbed. Lightweight HoverSpring™ foam features high-rebound performance for industry leading underfoot comfort. An outsole made of a premium soling compound, utilizing a repeating tread design that maximizes surface contact with square leading edges to provide slip resistance where wet and oily contaminates are present. Meets the SRO requirements of ASTM F2413, F2892, or F3445, when tested to F2913. Microban technology provides an extra layer of protection on footwear fabrics against unpleasant odors, stains, and deterioration caused by bacteria and fungus.
