The Gel Kayano 32 is Asics at its most dependable: a premium stability running shoe built for racking up everyday miles in comfort rather than chasing pace. It is a support shoe, but a modern one. Instead of a hard medial post pushing back at your arch, it leans on soft cushioning and a guidance-led geometry that gently keeps your foot tracking straight as you tire. At a 8mm drop it sits in classic daily-trainer territory, and the plush heel makes it forgiving for heel-strikers logging long, steady runs. At 305g it is on the heavier side, so this is a comfort and protection shoe first, not a quick one. The trade-off for that smooth, planted ride is an RRP of 180 pounds, which makes it one of the dearer daily trainers out there. If you overpronate mildly and want a cushioned shoe that holds together for months of training, it earns its keep. If you want the same softness without the support, the neutral Gel Nimbus 28 is the sibling to look at. Coming from the Kayano 31? The 32 is a refinement, not a reinvention.
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.
A side-by-side comparison makes the trade-offs between two running shoes easy to see, but the right pick still depends on how you run. Weight and stack height shape the feel underfoot: a lighter shoe with a lower stack feels nimble and fast, while a heavier, taller stack gives a softer, more protective ride for long miles. Heel-to-toe drop changes where you feel the load, with lower drops asking more of the calves and Achilles.
The price figures update from the UK retailers we track daily. The best price now is the cheapest tracked price we can currently link to, the 90-day low shows how cheap the shoe has been recently, and the 30-day average tells you whether a price is a genuine drop or just the going rate. Coverage is partial rather than complete, so always confirm the final price and your size on the retailer site, and set a price alert on the model you want so we can email you the moment it drops.
