Gel Kayano 33 vs ForeverRun Nitro 2

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 ForeverRun Nitro 2 is Puma's answer to the modern stability question: hold your foot steady without a hard medial post, and cushion it enough to still feel good at the end of a long run. It is a road stability trainer built for higher mileage, with a 38mm heel and 28mm forefoot giving you a genuinely deep, protective platform and a traditional 10mm drop that most heel-strikers will settle into fast. The support comes from a wider, structured build and Puma's RunGuide sidewalls rather than a firm post, so it guides rather than corrects. At 295g it is not light, and you feel that. This is a shoe for steady, controlled miles, not a shoe you will want to pick up the pace in. If you overpronate mildly or just want a stable, cushioned daily workhorse that stays composed when you are tired, it earns its place. If you are chasing lighter, springier stability, look at the newer wave of soft-support trainers instead. It replaces the ForeverRun Nitro 1 and keeps the same job description.
