The Y-3 Shiku Run takes inspiration from classic running styles from adidas’ extensive archives. The upper combines double-layer black mesh with off-white suede overlays along the forefoot and eyestay. Integrated into the speed lacing system is a red cord that wraps over the toe box and around the black of the heel. Lightweight cushioning arrives via an EVA midsole, supported underfoot by a two-piece rubber outsole with debossed Y-3 branding under the heel.
