The fit and feel of a running shoe in a casual everyday walker? What's not addictive about that? The new Addiction™ Walker now comes with durable, energy-returning MoGo midsole cushioning, a more supple full-grain leather upper, strong support, and reliable slip-resistant outsole. This shoe provides sturdy support mile after mile by supporting low arches and keeping pronation under control. 11.9 oz. The full leather version of the Brooks Addiction mesh running shoe.
