The upper of this sleek looking $100 Shox walking shoe was pretty nice. Designed for fitness walkers this shoe featured a molded lightweight synthetic leather and mesh, shox tech with a walking specific curved heel radius, Phylon forefoot frame that holds inboard/outboard PU sicklier with forefoot air unit and an outsole with combination solid and durable rubber compound with visible air window in the forefoot. Overall nice looking 2003 offering from Nike.
