Caterpillar Men's Excavator XL 6" WP Composite Toe. The ExcavatorXL is the ultimate work boot for heavy industrial jobs. Ten years ago, Cat Footwear introduced its proprietary SuperDuty iTechnology: where welted durability meets athletic comfort. With the ExcavatorXL 6” boot, that technology has evolved to include a new EaseHD (heavy duty) footbed, iTechnology construction, and an extended last for even more room and comfort for your feet. The impressive comfort features are equally matched by the protective, safety technology that the ExcavatorXL offers, including a lightweight, yet highly protective, composite toe, electrical hazard features, and waterproof construction. The T1410 outsole is engineered for extreme slip resistance and includes our exclusive SRX outsole compound which exceeds industry standards at reducing the risk of slips and falls in the workplace. This work boot is also powered by ERGO Technology which combines biomechanics, ingenuity, hardened durability and trademark grit to create a shoe that will provide comfort all day long. And, it’s all backed up with a 60-day comfort guarantee.. ASTM F2413-11 Composite Safety Toe protects against impact or compression. ASTM F2413-05 1/75 EH Electrical Hazard Protection rated to protect against open circuits up to 600 volts in dry conditions. Waterproof, Full Grain Leather Upper keeps feet dry and protected, and provides long-term durability.
