The 'Solar Red' sneakers were part of the June 2016 Ultra Boost Uncaged collection, which consisted of five different colorways. These sneakers had a Primeknit upper that showcased a pixelated blend of solar red and orange. In a move to create a more simplistic aesthetic, adidas decided to remove the TPU Three Stripes from the Ultra Boost Uncaged line, resulting in a minimalist feel. The remaining colorways in the collection were 'Grey,' 'Core Black,' 'Clear Grey,' and 'Shock Red.'
