The Glycerin 23 is Brooks at its plushest: a max-cushion daily training shoe built for the soft, unhurried side of your week. This is not a shoe chasing a personal best. It is the one you reach for on recovery days, easy miles and long relaxed runs when you want your legs coddled rather than told to work. The DNA Tuned midsole is deep and forgiving, with a tall 38mm heel stack and a moderate 8mm drop that suits heel and midfoot strikers alike. At 300g it is not light, and it never pretends to be fast, so if you want a snappy tempo shoe look elsewhere. What you get instead is comfort you can rely on, mile after mile, in a neutral running shoe that feels like it was tuned for pure cruising. If you want the same plush ride with a touch of support, the Glycerin GTS 22 adds guide rails. We rate it as one of the most dependable soft daily trainers going.
The Magnify Nitro 3 is Puma's big, soft, everyday max-cushion running shoe, and at £140 it undercuts most of the plush daily trainers it lines up against. This is the shoe you reach for on easy days, long runs and recovery miles when your legs want protection more than speed. The NITRO foam midsole is tall and forgiving without turning to mush, and Puma's PUMAGRIP outsole is genuinely excellent in the wet. At 287g it is not a light shoe, and you feel that on faster efforts, so treat it as a cruiser rather than a tempo tool. It runs neutral, with a 10mm drop that suits heel and midfoot strikers. In our view the real story is value: you get proper max cushioning and grippy, hard-wearing rubber for less than a Gel Nimbus 28 or Glycerin 22. If you want soft daily miles without paying £170, it belongs on your shortlist.
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.
