Adidas Adizero Prime X 3 Strung

A 50mm, illegally-tall super trainer with three layers of Lightstrike Pro and a full carbon plate that delivers a springy, trampoline-like long-run ride. Reviewers found it best for bigger runners who can compress the firmer foam and unlock the plate. Lighter runners and anyone wanting a nimble shoe will find it bottom-heavy and clunky.

Who it's for

Reach for the Adidas Adizero Prime X 3 Strung for everyday training miles and long runs. It's a neutral shoe, best for runners with an efficient stride who don't need pronation support. The tall, soft stack favors comfort over ground feel. That's great for high mileage and bigger runners, less so for racing snappiness.
