Recommend regular size fit. The silhouette has changed since the last edition of Nike x sacai ID Waffle. VaporWaffle combines the classic running shoes "Pegasus" from 1983 and the innovative "Vaporfly". The upper composes nylon, leather and suede materials. Dual branding on the tongues, side Swooshes, and intertwined laces represent Chitose Abe-helmed's branding concept "Twice as nice." A layered midsole and Waffle outsole complete the design.
