Iron Age. The very name conveys long-lasting, reliable strength, quality, durability and affordability. And since 1817, that's exactly what people have felt in Iron Age shoes. It's about doing it with style and comfort, adding high-end touches like leather uppers, without the high-end price tag. These Thermo Shield 8'' Internal Met Guard Boots feature: a composite toe cap, a full grain leather upper, a Dri-Lex Zig-Zag lining and a dual layered open cell PU insert. They also feature a Vibram Alpha TC4 Plus heat resistant rubber sole and Flex-Met - an anatomically shaped appliance permanently inserted internally in the instep area of the shoe and designed to provide additional protection to the instep area, meeting the ASTM F2413 standard for Metatarsal footwear. There are some speacial features, too - Goodyear welt construction with genuine leather welt and full leather insole, electrical hazard protection, Kevlar stitching, plus additional insole included in box. Material: Leather, Rubber.
