adidas Men’s Y-3 Runner 4D IOW ‘Bliss’

adidas Y-3 Runner 4D IOW ‘Bliss’

The Y-3 Runner 4D IOW ‘Bliss’ represents Yohji Yamamoto’s modern design language at its finest — a fusion of avant-garde aesthetics with adidas’s most progressive performance technology. This silhouette features a removable, modular upper system (“IOW” = In/Out Wear), allowing the shoe to shift between a lightweight inner bootie and a weather-ready outer shell for adaptable all-season use.

The signature adidas 4D midsole, crafted using precision digital light synthesis, provides responsive cushioning and stability while creating a striking architectural profile. Neutral Bliss tones balance Y-3’s experimental structure, delivering a clean, elevated look suitable for both streetwear and functional wear.

Finished with minimalist Y-3 branding, premium textile construction, and a durable Continental rubber outsole, the Runner 4D IOW ‘Bliss’ stands as one of the line’s most innovative and collectible designs.
