As the name suggests, the upcoming “Earth” makeup is expected to feature earth tones throughout the model with a tonal brown Primeknit upper and on the full-length Boost midsole. An even darker shade of brown covers the sockliner while a yellow and gum outsole completes the look. Note that early images have yet to surface, but the Yeezy leaker account has provided a visual representation of the upcoming style.
The “Earth” Adidas Yeezy Boost 350 V2 is currently scheduled to drop sometime in Early 2020 for the usual $220 price tag.
