The Hyperboost Edge is adidas going all in on soft, high-stack comfort for everyday miles. It is a max-cushion road running shoe built for one job: soaking up impact and keeping your legs fresh over long, steady distances. With a 44.6mm heel and a moderate 6.5mm drop, there is a lot of foam underfoot, yet at 247g it stays lighter than most shoes this tall, so it never feels like lugging bricks. There is no plate here, and adidas has not tried to make it a do-everything trainer. It is a cushioned cruiser, plain and simple. If you want the plush, protected feel of adidas's classic Ultraboost but with a taller, more modern stack, this is the natural step up. We rate it as a genuine long-run and recovery-day tool rather than a daily quiver of one. Firm-ride fans and anyone chasing turnover will want something snappier, but for eating up easy volume in comfort, it delivers.
The Wave Sky 9 is Mizuno's plush, max-cushion daily trainer, a soft running shoe built to soak up easy miles and long runs rather than chase pace. With 44.3mm of stack under the heel and a moderate 6.2mm drop, it plants a deep, protective platform between your legs and the road, and that is exactly where it does its best work. At 295g it is a substantial shoe, so nobody will mistake it for a tempo tool. That heft is the trade-off for the comfort. If you want a neutral cushioned trainer to protect tired legs across a marathon build, or a plush recovery-day cruiser, it earns its place. If you already run in the Asics Gel Nimbus 28 or another pillowy daily trainer, the Wave Sky 9 sits squarely in that same comfort-first bracket, and we rate it as an honest, dependable option rather than a flashy one.
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.
