When the weekend calls for some serious foot work, the Union Waterproof Boot steps up with outstanding comfort and toughness. The outsole with Vibram® XS-trek formula provides excellent grip and balance, so you can feel confident traversing wet or dry terrains. And the eVent® BBP Waterproof lining gives you all the more reason to ford that stream. Did we mention comfort? A new Ortholite® X-25 footbed gives you the kind of "–aah” you feel right away, and cushioning you feel all day.
