Having showed a preference for the Ultra Boost during past collaborations, Japan-based brand kolor and adidas reconnect in 2017 for another go ‘round. Featuring two sneakers – a traditional Ultra Boost and an Ultra Boost Uncaged – we focus on the latter model. Anchored by woven Primeknit construction in a blue tint, the design is accented with Tech Grey throughout the upper. Metallic silver on the heel cage system provides some eye-candy that will surely make heads turn. The Three Stripes brand keeps it classy with a white Boost midsole to balance out the overall look of the shoe. kolor branding appears on the heel to complete the show.
