EVA foam has been compression-molded to create cushioning footbeds of these premium men's safety toe boots, softening your stride. The nylon shanks support steps, lifting muscles to prevent strain and pain. Together, they give feet the strength and softness they need. Goodyear welt construction was used to attach the Vibram lug outsoles to the uppers of these Wolverine Novack boots. Durable Goodyear welt stitching means soles can be repaired as needed, which won’t be often because they're built to last. The lugs on the rubber soles bite deeply to give you traction. They’re also resistant to electrical hazards and made to absorb electricity to keep you safer, and they feature a lightweight composite safety toe cap for high-quality toe protection.
