The adidas Yeezy Powerphase Quiet Grey is a part of the collaboration between adidas and Kanye West's Yeezy brand, inspired by vintage athletic footwear. This model features a fully grey upper made from leather, with subtle Yeezy branding embossed on the side panel and 'Calabasas' lettering on the quarter panel. It incorporates perforated detailing forming the iconic three stripes and toe box, complemented by an additional Adidas logo on the heel of the rubber outsole. Released at a retail price of $120 on 18th September 2019, the Quiet Grey variation showcases a suede base, minimally styled with perforated Three-Stripes, tonal lacing, and a signature logo window. The gold foil 'Calabasas' lettering highlights the quarter panel, while the split rubber cupsole maintains a cohesive single-hued scheme.
