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.
The Bondi 9 is Hoka's maximum-cushion daily running shoe, the plushest, most protective trainer in the range. This is not a speed tool and it never pretends to be. It is built for one job and does it well: soaking up impact mile after mile so your legs finish easier than they started. At 297g with a 5mm drop it is a substantial shoe, and you feel that heft, but the reward is a deep, forgiving stack of foam and one of the most stable max-cushion platforms on the road. The foam in this version runs a touch softer and more balanced than older Bondis, so the ride feels less firm underfoot. We rate it as a recovery-day and easy-miles specialist, and a genuinely good option for heavier runners, tired legs and anyone who spends long hours on their feet. If you want the same brand cushioning with less weight, the lighter Hoka Clifton 10 is the natural alternative.
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.
