The Altitude OX I Waterproof is a great looking men's performance boot. Not only is it fully waterproof thanks to its Dri-Tec technology, but is also extremely comfortable because of the OrthoLite® Impressions insole which takes the shape of your feet over time to create a customised and comfortable fit. The Michelin® outsole adds the final durability, stability and traction needed in the ideal outdoor crossover shoe.
