Adidas Adizero Prime X 4

The continuation of Adidas's rule-breaking Prime X line, stacking Lightstrike Pro past the legal limit with Energyrods for maximum propulsion. It suits long marathon-pace efforts and runners chasing the biggest possible cushioning, not sanctioned races. A statement shoe that trades stability for bounce.

Who it's for

Reach for the Adidas Adizero Prime X 4 for long runs and race day. 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 — great for high mileage and bigger runners, less so for racing snappiness.
