adidas combined performance and style when they debuted the Ultra Boost earlier this month, calling it "the greatest running shoe ever". Made with the ultra-breathable PrimeKnit material and their innovative Boost technology, it has already been the talk of athletes and sneaker lovers alike. Not long after its release, the Three Stripes brand has announced plans to give the new silhouette a fashion forward makeover. The Ultra Boost Collective will be a limited-edition capsule collection featuring designs from longtime adidas collaborator Stella McCartney, Kris Van Assche, kolor's Junichi Abe, and adidas Creative Directors Dirk Schönberger and James Carnes. Sneakers from the adidas Ultra Boost Collective will become available staring in May and be released throughout the year at select retailers. Additionally, launch events will be held in each designer's city – London for McCartney, Paris for Van Assche, Tokyo for Abe and Berlin for Schönberger and Carnes. Stay tuned for more details as they come.
