The Iron Ranger Boots from Red Wing Heritage have been protecting the feet of miners for more than a century, so there's a good chance they can protect yours. Premium Amber Harness leather is used for the upper section, with a double layer over the toe for added protection on the job. A leather insole and cork midsole conform to your foot's natural shape, letting these boots become more comfortable over time. A steel shank throughout the midsole increases both stability and support for those long stretches of time spent on your feet. Nitrile Cork soles won't crack and lose durability after a few years like all rubber soles sometimes do. Triple stitched uppers and a Goodyear Welt construction ensure that these boots stand the test of time.
