Built for rough, outdoor work, Danner Mens Gritstone Waterproof Work Boots combine proven work-boot design 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. Danner Dry waterproof membrane technology delivers a breathable waterproof barrier to keep feet dry and comfortable while working. Polyurethane footbeds provide comfortable cushioning. 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.
