With 600 grams of cold weather protection, a fully waterproof build, and a 90° heel that locks into ladders, this winter workhorse keeps you warm, dry, and ready for anything. It’s built with barnyard-resistant BRUNT FARMGUARD™ leather that repels rain, mud, oil, piss, and sh*t, and features a resoleable Goodyear welt construction, a nano composite safety toe, and an innovative slip-, oil-, and high-heat-resistant resistant outsole.

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

FREQUENTLY ASKED QUESTIONS

Because of their reinforced build, welted boots are built to take a beating and they provide a higher degree of stabilization for your foot and ankle which makes navigating uneven footing much easier. And because of the mechanical bond created in the welting process, a Goodyear welt has best-in-class waterproofing, plus a resoleable design that allows you to replace the outsole to extend the overall life of the boot.

When it comes to a welted boot, think uneven terrain and unpredictable conditions. A welted boot is incredibly durable by nature and is best suited for heavy-duty jobs. To name a few specific trades who would benefit from a welted boot: road workers, commercial builders, pipefitting and welding, resource extraction, railroad, linemen, and waste workers.

A Goodyear welted work boot features an additional midsole layer that’s built into the boot to create torsional rigidity for additional stability and durability. This welt is formed by connecting the upper part of a shoe to the midsole of the shoe in a three step process: stapling the upper to the insole, stitching the upper to the insole, and then stitching the upper and the midsole together. This physical entanglement of fibers creates a very strong mechanical bond between the two main parts of the shoe, and provides a very durable build with a high degree of waterproofness. It also allows the outsole of the boot to be replaced—or “resoled”—after extended periods of hard use.

    Warm and comfortable

    I always wore danner boots but decided

    To try the insulated brunt’s and I work in -30 weather and kept my feet warm. Definitely will be buying another pair of non insulated. I’ve had them 2 weeks now and no complaints

    Mulder Insulated Boots Are Awesome!👍

    I love these Mulder insulated boots. They feel no different than the non insulated ones I have. They are taller and will help in the snow here in MN! I am so glad I purchased them when I did! I hope these return /restock as a regular item, so I can get them again.
