The J&D Collective x UltraBoost 1.0 'Core Black' was created as part of the adidas Ultra Boost Collective program in 2015, with the collaboration of adidas creative directors Dirk Schönberger and James Carnes. This particular version of the Ultra Boost 1.0 stands out from the regular model by utilizing Dyneema fiber in the construction of its Primeknit upper, along with featuring a distinctive snakeskin pattern on the midfoot cage and a leather tongue. To add a personal touch, the shoe's tan insoles are marked with the names of the two designers. In June 2015, this exclusive sneaker was made available at adidas Consortium accounts, accompanied by a white variation of the same design.
