Timberland Pro Endurance EV 6 Inch Waterproof Comp-Toe Work Boot TB0A5YXU214. We didn’t name these work boots “Endurance”by accident—they truly live up to it. The newest addition to this iconic line has been refreshed with modern materials and a refined design, delivering the durability, protection, and comfort you need to power through tough workdays. These boots feature premium Timberland full-grain waterproof leather uppers, now enhanced with molded TPU overlays and ultra-durable Ever-Guard leather reinforcements for added strength, along with internal waterproof membranes that offer top-tier water resistance and protection against blood-borne pathogens. They also include composite safety toes, internal Anti-Fatigue Technology polyurethane midsoles for superior shock absorption and energy return, and puncture-resistant plates. Breathable, moisture-wicking linings made from ReBOTL fabric—composed of at least 50% recycled plastic—are treated with an antimicrobial layer to manage odors. The boots are finished with non-marking Timberland PRO rubber outsoles that resist heat, oil, slips, and abrasions, and feature Ladder Lock™ heels for extra grip on ladder rungs.
