Just last month, adi crafted a special rendition of the Speedfactory-made AM4 to pay homage to Billy Jean King for this year's US Open. Now the Three Stripes are taking the AM4 back to the City Series, this time taking cues from the vast expanse that is the city of Tokyo. Dubbed the AM4TKY, the upcoming drop features the UltraBOOST-like styling of past AM4 drops and includes a grey mesh base with black accents, reflective details, and a white BOOST midsole. As far as tech goes, 'flexible tension patches were digitally mapped onto the shoe upper' and connect to the eyestay for stability. A new Torsion bar — which was redesigned and digitally embedded — also floats within the sole while doing away with the stiffness associated with adhesives.
Tokyo's version of the AM4 will drop in stores and online come September 20 for $200 USD.
