The JB Goodhue Ironworker is a boot that is built to last. The JB soles are welted on, which means they are a seamless fit with the shoe and your JB Goodhue boot will last, compared to soles that are simply glued on. The JB outsoles themselves are sprayed with an oil-resistant compound to keep your feet securely grounded. Ironworker has a full-grain leather upper, to contour to your feet. To make the shoe fit your feet perfectly; the Ironworker laces start at the toe. The leather tongue also adds extra padding and will wear well over time.
