The sacai x Nike VaporWaffle ‘Sail Gum’ combines a white nylon base with off-white suede and leather overlays, inspired by the Vaporfly and original Pegasus. Doubled laces and tongues, co-branded woven tag, and stacked foam midsole with split detailing at the heel offer a unique design. The waffle-traction gum rubber outsole provides excellent grip for everyday wear.
