Our Verdict

adidas Adizero Adios Pro 4

Diadora Gara Carbon 2

The adidas Adizero Adios Pro 4 and Diadora Gara Carbon 2 are both carbon-plated racers that deliver different experiences in the same race-day category. The adidas is lighter and features a more responsive midsole, offering an explosive toe-off that makes it a go-to for runners chasing aggressive splits and pure speed. However, that performance focus comes at the expense of stability, with the adidas feeling a bit more precarious underfoot, especially during longer efforts or when form starts to break down. The Diadora, in contrast, is soft and cushioned, but not overly so like the adidas. It finds a middle ground that many runners will appreciate.
