Built for rough, outdoor work, Danner Mens Gritstone Waterproof Alloy-Toe Work Boots combine proven work-boot design and safety-toe protection with modern construction. An update on Danners popular Quarry work boots, the Gritstone is built around Danners Bi-Fit platform. Replacing older platforms consisting of heavy steel shanks, midsoles, and lasting boards, the Bi-Fit provides lightweight support and protection underfoot while offering cushioning and stability throughout the heel and flexibility in the forefoot. Quality-tested, full-grain leather uppers feature triple stitching throughout for exceptional durability. Lighter than a steel toe, the Gritstones alloy toe meets or exceeds ASTM F2413-11M I/75 C/75 EH and ASTM F2413-11 F I/75 C/75 EH workplace standards for great protection at the site. Danner Dry waterproof membrane technology delivers a breathable, waterproof barrier to keep feet dry and comfortable while working. Polyurethane footbeds provide comfortable cushioning under the feet. Handcrafted Stitchdown construction creates a wider platform under the feet to deliver first-rate durability and stability, along with the ability to resole the boot down the road. The Gritstones 610 last creates a snug fit through the heel with ample toe room for a boot with more support and side-to-side movement. Vibram Gritstone outsoles provide oil- and slip-resistant traction that releases debris to help ensure solid footing on the job site. Imported. Height: 8. Avg. wt.: 4 lbs./pair.
