Yohji Yamamoto and adidas will be expanding their Y-3 lineup with two iterations of the all-new Ratio Racer, which was originally previewed at a Y-3 fashion show earlier in the year.

One pair comes dressed in Core Black and the other in Footwear White. Both are constructed with a Primeknit upper, sock-like ankle collar, unique lacing system and Y-3 branding on the tongues and also seen in a repeating print on the outsole.
