Featuring a classic two-tone look, the 550 'Sea Salt Black' is a retro basketball shoe. Built with leather, the shoe's upper appears in white, with tonal suede overlaying the forefoot and a microperforated midfoot overlay offering breathability. The branding adds contrast in black, including the signature 'N' logo on the side wall, while underfoot, an EVA wedge in the rubber cupsole offers cushioning. A black rubber outsole is included for traction.
