UltraBoost Uncaged 'Grey'

adidas launched this grey colorway of the Ultra Boost Uncaged in May 2017. This simplified version of the Ultra Boost arrives without the midfoot TPU overlay, though an internal support system maintains the structure of the heather grey Primeknit upper. The matching flat laces are specially designed and executed in a tiered arrangement for enhanced comfort and stability. The heel stabilizer continues the grey color scheme, while the Boost midsole and Continental Rubber outsole deliver contrasting hits of white and black.
