Danner used the lightweight, agile Trailguard platform from their hiking boots to engineer the Danner Vicious Brown work boot to be nimble and tough from the ground up. This new last is designed to cup your heel for a secure fit while offering a little more room in the toe box to accommodate feet that are carrying heavy loads or changing directions quickly. It also comes with a dual density EVA midsole for extra shock absorption and comfort. The oil and slip resistant outsole have a low profile 90 degree heel making it versatile enough for indoor and outdoor work. but for really tough jobs it has an abrasion-resistant heel cap and a waterproof, breathable GORE-TEX® liner.
