The designers of the first 990s were tasked with creating the best running shoe on the market. The 990v6 MADE in USA model draws on this original mandate, with a series of performance-inspired updates. The upper dispenses with the standard saddle in the midfoot, allowing the suede and synthetic leather upper to flow from heel to toe across the mesh base for a fast, streamlined look. While the design evolution represents one of the most drastic changes between generations of 990 models ever seen, the real revolution is happening on the inside. The addition of FuelCell cushioning in the midsole means that the evolution of the 990 is not only visible, but also noticeable. - FuelCell foam ensures maximum propulsion to propel you forward - ENCAP midsole cushioning combines soft foam with a durable polyurethane rim to provide support that lasts all day long - Reflective details - TPU rear tab DESIGNER ID: U990 LT6
