M 990 GL6 Core Grey

The mission of the original 990 was to create the best running shoe on the market.
The MADE in USA 990v6 takes up this original mandate with a number of performance-enhancing adaptations.
The upper dispenses with the standard midfoot seam so that pigskin and synthetic overlays extend from heel to toe over the mesh underlay for a stealthy, aerodynamic look.
The new design marks one of the most drastic changes from one generation to the next.
Never before seen on the 990!
The biggest change is inside.
With the addition of FuelCell cushioning in the midsole, the new 990 looks as good as it feels.
