The Gel Nimbus 27 is ASICS at its most plush: a max-cushion neutral running shoe built for soft, protected miles rather than speed. This is the shoe you reach for on easy days, recovery runs and long efforts when your legs want padding underfoot and a forgiving ride. At 305g it is not light, and with an 8mm drop it sits in familiar territory for a daily trainer, but the appeal here is comfort, not pace. We rate it as one of the safest picks in the cushioned daily category, especially if you log steady mileage and value a shoe that feels the same in mile twenty as it did in mile one. It is a premium buy at £175 RRP, so it asks a lot up front. If you want the same soft, dependable feel in something a touch lighter and quicker, the Gel Cumulus 27 is the leaner sibling worth a look.
The Salomon Aero Glide 4 is the brand's big-cushion road running shoe, built for soaking up easy miles and long runs without asking your legs for anything back. With a tall 43.2mm heel stack and no carbon plate, this is a comfort-first daily training shoe rather than a racer. What sets it apart from most max-cushion rivals is the tall 11.7mm drop, which rolls you forward off a generous heel and suits runners who land heel-first. It is not the lightest shoe in the class at 250g, and it is not trying to be snappy. What you get instead is a soft, planted, protective ride that stays comfortable when the miles pile up. If you loved the Aero Glide 3, this is a familiar, refined take on the same idea. We rate it as a dependable cushioned trainer for steady runners who value comfort over pace.
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.
