adidas UltraBOOST 4.0 (Blue Heel)

BOOST’s fifth birthday will undoubtedly see a bunch of new shoes hitting shelves at a consistent clip. Helping to launch the onslaught is a ‘Blue Heel’ 4.0.

Mottled blue and grey Primeknit uppers are complemented by grey caging and splashes of blue on the – you guessed it – heel counters.

Rumoured to drop in spring, we’ll keep you posted with details as they come.
