Designed in collaboration with Transport for London, the adidas Transport for London x Micropacer R1 'Northern Line' sneaker pays tribute to London's oldest electric line, the Underground Northern Line. Unveiled in December 2018, this stylish sneaker features a leather sockliner, a nubuck and suede upper, a Boost midsole, and a signature pedometer. Each shoe showcases distinctive elements that salute the historic Northern Line, with one displaying a graphic inspired by the line and the other bearing the significant debut date of '18/12/1890'. This special edition sneaker symbolizes adidas' partnership with Transport for London and their shared commitment to honoring the city's rich heritage.
