The sacai x Nike VaporWaffle 'Sail Gum' is a fashion-forward lifestyle runner that combines elements from Nike's history and present. The upper is inspired by the Nike Vaporfly and the original Pegasus from 1983, with a white nylon foundation and off-white suede and leather overlays. Doubled-up laces and tongues, one with a co-branded sewn tag, are among Chitose Abe's distinctive embellishments. The shoe is supported by a stacked foam midsole with split design at the heel. A waffle-traction gum rubber outsole delivers great traction underfoot.
