New Balance developed the New Balance 990 sneaker over four years, with the goal of creating the ultimate performance runner in mind. It debuted in 1982 and has endured as a performance-focused running shoe ever since. This ‘Mint’ rendition is part of the fourth iteration of the silhouette, featuring an all-green colorway on a suede upper with perforated panels and tonal leather branding. A two-tone midsole with ENCAP technology is reinforced by a durable rubber outsole.
