The designers of the original 990 were charged with developing the greatest running shoe on the market. The MADE in USA 990v6 upholds its initial commitment with a slew of performance-focused improvements. The upper eliminates the traditional midfoot saddle, enabling the pigskin and synthetic overlays to flow from heel to toe across the mesh underlay for a quick, streamlined appearance. While the evolved design represents one of the most drastic modifications from one generation model to the next that the 990 has ever seen, the most significant advancement happens on the inside. With the inclusion of FuelCell midsole cushioning, the 990's progression is felt as much as seen.
