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 Brooks Glycerin 21 is a max-cushion daily training shoe built for one job: making your everyday miles feel soft, calm and comfortable. This is the plush end of the Brooks range, a neutral running shoe that leans into cushioning rather than speed. At 280g it is not light, and it will not snap you through a fast finish, but that was never the point. What you get is a deep, forgiving underfoot feel that holds up well over long easy runs and recovery days, and a 10mm drop that suits heel and midfoot strikers alike. We rate it as a dependable cruiser for runners who want protection and a smooth, quiet ride over anything sharp or racy. If the £165 price gives you pause, the cheaper Brooks Ghost 16 covers similar daily duty with a touch less plush. But if soft comfort is what you are after, the Glycerin delivers it honestly.
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.
