Introduced in 1982, the New Balance 990 was a game-changing sneaker, built with a spare-no-expense mandate to create the best running shoe on the market. Decades later, the sixth generation holds true to its original spirit with modern materials. Those include FuelCell foam for greater energy return and ENCAP midsole cushioning for both comfort and support. The upper, rendered here in olive green, is crafted from breathable mesh with pigskin and synthetic overlays and reflective accents for safety at night.
