Our Verdict
Nike Downshifter 14
adidas Adizero Pacer
The adidas Adizero Pacer and Nike Downshifter 14 are both budget shoes from rival brands, but the adidas is better suited to actual running because it's lighter and offers more cushioning. The Nike has a lower stack that results in more ground feel and a higher drop, while its broad platform and fully gusseted tongue give it the more stable and secure ride.
