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 Saucony Triumph 23 is the brand's premium max-cushion daily training shoe, built to soak up big weekly mileage in comfort rather than chase a fast time. It sits at the plush end of the neutral daily trainer market, with a tall 42.3mm heel stack and a soft, protective ride that rewards easy runs and long steady efforts. This is not a shoe you buy for speed. At 272g it is on the heavier side, and the 10mm drop plus generous cushioning steer it firmly towards comfort miles. What you get in return is a running shoe that stays kind to your legs at the end of a marathon block, when tired joints want padding more than pop. In our view it is one of the more dependable premium cushioned trainers you can buy, and a natural home for runners who log most of their week at conversational pace. If you already run the Triumph 22, the 23 is a familiar, refined step on.
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.
