Wave Inspire 21

Verdict

The Mizuno Wave Inspire 21 is a high-performing option in its class — a stability scoring 85/100 in SoleHunt's data-driven evaluation, drawing on 0 consumer reviews and 0 independent expert tests. Tipping the scales at 290g, it is standard weight for a stability. The 36mm heel stack — a generous stack — delivers a comfortably cushioned ride at 30 HC, returning 60% of impact energy and feeling responsive and lively underfoot. Geometrically, the Wave Inspire 21 runs on a high 12mm drop that cushions the transition for heel strikers, with a 24mm forefoot stack that maintains the traditional heel-elevated geometry runners with tight calves often prefer. Fit-wise, the toebox measures 92mm — medium-width, comfortable for most foot shapes — and the upper is available in D/2E widths. Wider stability shoe. Good for mild overpronators. The removable insole makes it compatible with custom orthotics. It is designed for mild overpronators, daily training, long runs, and performs less well for severe overpronation or speed work.
