Gel Kayano 33 vs Wave Inspire 21

The Gel Kayano 33 is Asics at its most reassuring: a premium stability running shoe built to log big, comfortable miles while keeping your stride honest when you tire. It is a max-comfort support trainer, not a speed tool. At 298g with a 39mm heel and 8mm drop, this is a lot of shoe, and it feels it underfoot in the best way. The FF Blast Plus Eco midsole is soft but composed, and the FluidSupport system replaces the old plastic guidance wall with a firmer, adaptive foam that steadies your ankle without shouting about it. In our view that is the story here: a stability shoe you forget is a stability shoe. It sits at the top of Asics' support range on price, and the £191 RRP is a real ask. If you want the same lineage for less, the Kayano 32 still does most of this. But for daily easy runs and long efforts where you want protection and quiet guidance, the 33 is one of the most complete support trainers on the road.

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.
