The Wolverine Durashocks ST boots were engineered from the inside-out to be a dependable work companion. Let’s take it from the top: A full-grain, suede nubuck leather upper is triple-stitched and ultra durable. The mid-cut provides ankle support as you move quickly through a work zone, while direct-attach construction seals out water. Steel eyelets and hooks mean your feet will be snug—and the boot will stay in place all day long. The steel-toe meets electrical hazard safety standards for the ultimate protection. A removable, dual-density polymer footbed adds cushioning and stability. Fiberglass shanks stabilize the feet, reducing fatigue, but are 75% lighter than steel. The polyurethane outsole is not only high-traction, but absorbs shock to minimize damage up through your leg. It kind of makes you want to stand all day Meets ASTM F2413-11 M I/75 C/75 EH.
