The Sacai x Nke VaporWaffle “Sail” is a collaboration between Chitose Abe’s high-fashion brand and Nke on a casual lifestyle shoe that fuses elements of Nike’s VaporFly and Pegasus styles. The “Sail” edition of the VaporWaffle is one of multiple releases imagined by Sacai and Nke in 2021, and one of the pair’s most versatile designs yet. The base of the upper is constructed in lightweight white nylon. Sail suede and leather overlays appear on the upper, as well. In true Sacai and Nke fashion, the “Sail” adopts a “double” aesthetic that finds two, dual tongues and laces, and a stacked, avant-garde-style foam midsole. Dual Sacai and Nke branding is found on the heel and classic "Nke Sportswear" and branding appears on both nylon tongue tags.
