Light on foot. Strong on performance.

Nitrogen-infused Mizuno Enerzy NXT cushioning provides a responsive feel underfoot, while Smooth Speed Assist geometry helps guide smoother heel-to-toe transitions.

The result is a shoe that feels stable, efficient, and easy to run in.

Comfort built in.

A redesigned engineered mesh upper combines breathability with stretch for a comfortable fit, while the updated heel collar improves security through the rearfoot. Premium X10 rubber helps deliver grip and durability across daily training.
