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 Vomero Premium 1 is Nike's most indulgent daily trainer, a max-cushion running shoe that takes the everyday Vomero name and pushes it well upmarket. You get a towering 50mm heel stack of ZoomX foam, the same bouncy compound Nike uses in its racers, plus four Air Zoom units underfoot for a soft, springy landing. It is built for easy miles, recovery days and long steady runs where comfort matters more than speed. At 326g it is a heavy shoe, and the RRP of 210 pounds sits at the premium end of the daily-trainer market, so this is a treat rather than a workhorse. If you want much of the same plush ZoomX feel for less, the Vomero 18 covers similar ground. But if you love a deep, cushioned ride and want Nike's softest foam under a max stack, the Premium delivers. We rate it as a soft-day luxury, not an everyday do-it-all.
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.
