The adidas Ultra Boost 3.0 Royal Blue is a stylish running shoe by adidas, known for its performance features and added comfort. The shoes have a PrimeKnit upper featuring a Royal Blue color scheme that covers the majority of the upper while the midsole appears in white and the outsole in black. The midsole incorporates adidas’ Boost technology which provides responsive cushioning and energy return, making the shoe ideal for running conditions. Other stand-out features on the shoe include a torsion system in the midsole and a plastic cage with the three stripes, that wrap around the midfoot to enhance stability and support during movement. One of the stand-out features of the adidas Ultra Boost 3.0 Royal Blue is the use of PrimeKnit material on the upper. It is lightweight and flexible, offering a sock-like fit that allows the shoes to adapt to the shape of your foot. The shoes were first released for retail in December 2016 priced at $180.
