The Nike Wmns Air Max 90 SD has a legendary history, originating in 1990, and is specifically designed for urban environments with its dynamic features. This particular version, known as the 'Dark Obsidian' for women, achieves a stylishly distressed appearance by incorporating a combination of distressed and full-grain leathers, suede, and TPU on the upper. The laces are accented by grooved eyestays and contrasting trim, and the classic logos further emphasize the brand's heritage. The underfoot experience is defined by a Max Air-injected midsole and a rubber Waffle outsole.
