The Katabatic Wind is Oboz's most technically advanced footwear yet. The next generation of Oboz Fast Trail hiking shoe features the Inertia of Motion (IOM) System made up of ACTNitro dual-density super critical foam and a forefoot carbon plate. These work together to propel each step so you can go faster and further. Prioritising weight and technical performance, the Katabatic Wind is for fastpackers who count grams and FKTs.
