Virgil Abloh's recent Off-White x Nike "Queen" collection for Serena Williams is apparently just the beginning of the designer's women's-focused output with the Swoosh.
According to leaker py_rates, Abloh will explore new territory in 2019 with a three-sneaker women's Waffle Racer pack. The range is expected to include "Black/Fuchsia/White," "White/Electric Green/Black," and "Vivid Sky/Black/Electric Green" colorways, although no images or renders are available at this time.
py_rates goes on to state that the three Waffle Racers are part of a wider women's Off-White x Nike collection which will include more footwear and apparel. The women's Off-White x Nike Waffle Racers are expected to drop in May 2019.
First introduced in 1973, the Waffle Racer was one of Nike's most influential early models and gets its name from its sole, which was famously invented by co-founder Bill Bowerman using a waffle iron. A 2017 Waffle Racer release is pictured below for reference.
