The Air Max 90 PRM Side A looks to the silhouettes connection to music for inspiration. Drawing from the idea of sampling, the shoe draws nine elements from previous models, with a moon graphic on the medial side, ostrich Swoosh branding and a cork insole. The laces are modeled after cartridge tape, while the heel sports prominent stitching. Underfoot, the midsole houses a visible Max Air unit in the heel, while the translucent outsole further plays to the theme.
