Following the unveiling of the Retro Boost and Qasa High, Y-3 has unveiled the Boost QR. The collaborative venture between Yohji Yamamoto and adidas sees an adaptation of the Qasa, with a more manageable outsole and slimmer silhouette. The sneaker features premium materials such as leather on the heel cage. Canvas and mesh make up the rest of the model, which is available in two colorways — black/white and black/khaki. Expect the sneaker to drop sometime soon.
