Wave Inspire 21 vs Wave Inspire 22

The Wave Inspire 21 is Mizuno's dependable stability running shoe, built for runners who want gentle support without a corrective, medical feel. This is a daily training shoe first and foremost: high 12mm drop, a firm and planted ride, and enough structure to keep a mild overpronator honest over the miles. At around 295g it is not light, and it never pretends to be fast. What it does well is turn up every day and hold its shape, which is exactly what a lot of runners want from their main trainer. In our view it sits in the same conversation as the Asics GT-2000 14 and the Brooks Adrenaline GTS 25: honest, supportive daily miles rather than plush luxury or race-day pop. If you overpronate a little and want a shoe that just works, it earns its place. Runners chasing a soft, bouncy ride should look elsewhere.

The Wave Inspire 22 is Mizuno's dependable stability trainer, a road running shoe built to keep you upright and comfortable over the miles rather than to chase a fast time. It sits in the moderate support camp: enough guidance to steady a mild overpronator, but calm enough that neutral runners who like a planted, structured ride can wear it happily. At 280g with a 7.6mm drop and 36.6mm of heel stack, it is a proper everyday workhorse, not a plated speed shoe. The Mizuno Wave guidance under the arch gives it that signature stable-but-not-clinical feel the line is known for. We rate it as one of the more honest daily stability shoes on the market: no gimmicks, no wall of hype, just a shoe that turns up for easy runs, steady miles and long training days. If you want a supportive daily trainer you can trust for a marathon build, it belongs on your shortlist. Compare it against the Wave Inspire 21 if you can still find last year's model on offer.
