UltraBoost Uncaged 'Clear Grey'
The adidas Ultra Boost Uncaged ‘Clear Grey’ released in March 2017. This simplified version of the Ultra Boost arrives without the midfoot TPU overlay, though an internal support system maintains the structure of the light grey Primeknit upper, accented with subtle flecks of orange and green. The matching grey flat laces are specially designed and executed in a tiered arrangement for enhanced comfort and stability. The partially translucent heel stabilizer continues the Clear Grey color scheme, while the Boost midsole and Continental Rubber outsole deliver contrasting hits of white and black.
