The Mulder Welted keeps you sure-footed on the most demanding jobsites. To support your foot and handle heavy-duty work, the Mulder features a resoleable Goodyear welt construction, and comes equipped with a slip- and oil-resistant TPU outsole, a fully waterproof design, and barnyard-resistant leather sourced from American steer. This workhorse also has all the trademark comfort you’ve come to expect from a BRUNT boot—including a triple-padded ankle collar, our custom triple-layer insoles, and an ultra-cushioned PU midsole.

Andy Mulder is a hardscape business owner based out of northwest Indiana where he and his crew are moving acres of earth every day and hardscaping some of the most valuable properties in the midwest. Since he was 15, Andy has pulled on a pair of welted work boots every morning before heading to work, and with that much first-hand experience, we knew he was the right guy to collaborate with on our first ever welted boot design. His years of working on uneven terrain in rough conditions helped us hone the Mulder into a boot that he can rely on just as much as the heavy machinery in his garage. —Eric Girouard, Founder + CEO
