Mizuno Wave Inspire 21

Mizuno Wave Inspire 21 review: what runners say

Fit

Runs slightly narrow; half-size up recommended. Forefoot volume has been widened compared to previous versions, accommodating wider feet as well.

Feel

Medium-cushioned ride with smooth transition: Enerzy NXT softens heel impact without eliminating road feel. The 12 mm drop favors heel strikers; the Wave plate delivers stability without weighing down the ride.

Durability

X10 Carbon Rubber outsole with minimal wear past 100 km in testing. Mizuno ranks among the most durable brands in the category; above-average lifespan expected.

Best for

Moderate-stability daily trainer for runners with pronation tendencies, heel strikers, recovery runs, and mid-distance. Versatile at uptempo paces as well; less suited for long runs beyond 20 km or structured speed sessions.

Weak points

Weight (approximately 292–295 g) is seen as a disadvantage against direct competitors. The 12 mm drop divides opinion: functional for those who need it, not recommended for runners seeking a more natural feel. Some report inadequate ventilation in warm conditions.
