The adidas Ultra Boost made its debut three years ago, and for this holiday season, the adidas Ultra Boost 1.0 OG will be making its return. The model introduced a popular style that is already in its fourth iteration, and it features the original Primeknit pattern that mixes black and grey hues. Detailed with a matching TPU lacing cage system and contrasted with purple heel overlays, the model is completed with a white Boost midsole and Continental outsole.
