Adidas' Adizero franchise has been going from strength to strength these past years, winning races left, right and centre. The company's race-ready lineup includes the Takumi Sen franchise, now in its tenth iteration, explicitly designed for 5-10k races.
Admittedly, it's a niche market compared to marathon runners, but considering the growing running population, it makes sense for Adidas to have a shoe like the Adizero Takumi Sen 10 in its roster.
