These Rocky Waterproof 6in. Steel Toe Metatarsal Guard Work Boots provide maximum protection in the most extreme conditions. These boots are the perfect protection to wear for welding or working in an environment with precipitation where temperatures fluctuate, where objects might fall or where sparks fly on a regular basis. The steel toe is ASTM rated to protect against 75 lbs. of impact and compression, while the metatarsal guard is ASTM rated to deliver solid protection to the metatarsal portion of your foot. Heavily oiled full-grain leather uppers are combined with the Rocky waterproof system to keep your feet dry regardless of rain or leaking water. Triple-stitched fire-resistant reinforcements and safety-stitched toes, along with flame-resistant laces, keep feet safe from sparks and flames. The removable Rocky EnergyBed inserts with memory foam provide shock-absorbing cushion with every step, so your feet stay comfortable all day long. ABS shanks deliver arch support and keep you steady on your feet, while high-heat, 3mm lugged outsoles provide traction, heat resistance and cushioning support. The high-abrasion thermoplastic polyurethane kickoff tabs help you remove these boots quickly after a long day's work. The Goodyear welt construction is not only durable, but also economical. It allows you to replace soles when necessary, so you don't have to buy a whole new pair of boots. These boots are a superior choice for protective footwear.
