Distinguished by Chitose Abe’s signature doubled design elements, the sacai x Nike VaporWaffle ‘Black Gum’ blends heritage inspiration with modern experimentation. Drawing influence from the Nike Vaporfly and the original 1983 Pegasus, the silhouette is presented in a sleek monochrome palette. The layered upper combines black nylon with suede and leather overlays at the heel and forefoot, adding depth and texture. Underfoot, a sculpted foam midsole with split heel detailing provides cushioning and stability, while a gum rubber outsole delivers reliable traction. Co-branded accents on the heel tab and sockliner highlight the collaborative identity between sacai and Nike.
