Two whites, only one of which was chosen. Cloud White is a dyed colour; Non Dyed is the raw shade of the yarn as it comes off the machine, slightly warmer and less even. Setting them next to each other on the same Primeknit upper produces a subtle two-tone effect that no amount of colour matching could replicate, and it makes the shoe look softer than a single flat white would.
This is a women's exclusive on the 4.0 pattern, with a synthetic cage at the midfoot integrated into the lacing to deliver lateral support and a full-length Boost midsole underneath for energy return. It arrived in January 2019 at $180. Skipping the dye stage on part of the upper also skips one of the most water-intensive steps in shoe manufacturing, a thread adidas pulled on repeatedly through the following years.
