Harmonic midsole geometry reduces muscle fatigue

The 990s original designers were tasked with creating the single best running shoe on the market. The finished product more than lived up to its billing. When it hit shelves for the first time in 1982 the 990 sported an elegantly understated grey colorway, and a then unheard of three-figure price tag. For avid runners and ahead of the curve tastemakers alike, the 990 was a mark of quality and superior taste. There have been updates to the design since 82, and more color options, but the 990s aspirational status symbol aura has never changed. Simply put, the 990 is the shoe so good, that weve never stopped making it. The FuelCell 990v6 for kids brings big impact to small feet.
