Adidas Adizero Boston 13 Flash Aqua

Flash Aqua is the bright take on the Adidas Adizero Boston 13, the shoe that sits between Adidas's daily trainers and its racers.

Firm, responsive and built to take mileage, the Boston is what most runners end up using two or three times a week: steady runs one day, a tempo block the next. It is the least fussy shoe in the Adizero family and the easiest to justify.
