By incorporating top-of-the-line materials like GORE-TEX® and Vibram® with a weight-saving platform, Danner® made the Vicious tough, versatile work boot feel like the kind of boot you want to put on at the end of a long day. 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. It also comes with a dual-density EVA midsole for extra shock absorption and comfort. The oil- and slip-resistant outsole has a low profile 90-degree heel making it versatile enough for indoor and outdoor work. For really tough jobs it has an abrasion-resistant heel cap, an all-leather upper, a non-metallic safety toe and a waterproof, breathable GORE-TEX® liner.
