Surfacing on Instagram user’s @kaiweikaiwei‘s profile, the adidas UltraBOOST sees a striking red BOOST sole. The new iteration also features a predominantly red colorway, with the upper constructed from red and black Primeknit. While the cage and laces also follow in the red colorway, the heel case is rendered in black for a contrasting look. So far there is no official word on when the red adidas UltraBOOST will drop. In the meantime, check out the latest models here.
