Summary Retail: 220€ - Availability: sold out - Resell value: 320€ - Size: 0.5 small - Release: 2015 - Verdict: Adidas' masterminds behind the highly successful Ulta Boost Dirk Schönberger and James Carnes (yes, that's why it is called J&D pack) designed this very limited capsule collective pack. A timeless black colorway has been pimped by using high-quality materials. It was the first time the plastic cage has been replaced by a leather cage with 3M stripes. Details like leather insoles make this release even more special. Needless to say that this Ultra Boost sold out in seconds no matter the high retail price.
