Gel Kayano 31 vs Structure 26

The Gel Kayano 31 is Asics at its most dependable: a premium stability running shoe built to soak up the miles and keep your stride honest when fatigue sets in. This is the shoe a lot of runners reach for when they want support without feeling strapped into a brace. The guidance built into the midsole works with you rather than against you, so the ride feels smooth and planted rather than corrective. At 310g it is a properly substantial daily trainer, so it is not the shoe for chasing splits, and the 10mm drop suits runners who land towards the heel. We rate it as one of the most polished stability daily trainers you can buy, and the cushioning has the kind of long run comfort that earns its place in your rotation. If you want a lighter, cheaper Asics with similar support, the GT-2000 14 is the value pick. At £170 the Kayano asks for a premium, so it has to be the support shoe you train in most weeks to justify it.

The Nike Structure 26 is a steady, no-drama stability running shoe built for everyday miles rather than fireworks. It is a support daily trainer aimed at runners who want gentle guidance underfoot without a heavy-handed medial post. At 298g it is a substantial shoe, and that weight tells you what it is for: long, easy, repeatable training runs where comfort and a planted feel matter more than speed. The 10mm drop and 36.1mm heel stack give you a familiar, protective ride that suits heel strikers well. It is a sensible step on from the Structure 25, keeping the supportive character while smoothing out the ride. We rate it as a dependable workhorse: not exciting, but exactly the kind of stability daily trainer you reach for when you just want to clock the miles and stay comfortable. At £130 RRP it sits in the mainstream support bracket and competes squarely with the established names.
