The Y-3 Qasa is now more comfortable than ever. Everyone's favorite high-end runner just received a major upgrade by way of adidas' signature Boost technology. After the debut of the Yohji Boost this past summer, it was only right to replace the Qasa's EVA midsole with the superior cushioning system, and adidas made sure to go H.A.M. with a full-length Boost. The debut pair features a Hawaiian floral print textile upper and drops next month. Sole Collector got hooked up with a pair early and you can peep the rest of the detailed shots here.
