Nike Air Span+ 6The Air Span 6 has everything you look for in a running sneaker: stability, flexibility, and a cushioned ride. They have an open sandwich mesh upper with supportive overlays and soft linings, full-length Air-Sole unit to absorb impact, BRS 1000 heel for longevity, and a solid rubber Waffle outsole for superior traction. Nike obviously crossed the finish line with the Air Span 6, now you can do the same.
