The Ultraboost 23 is adidas at its most comfortable: a plush, heavy daily running shoe that leans as much into all-day wear as it does into your easy miles. This is not a shoe built to chase pace. At 310g it is one of the heaviest trainers you will run in, and you feel every gram when you try to push. What you get in return is a deeply soft, springy Boost midsole, a hard-wearing Continental rubber outsole with proper grip, and a knit upper that hugs like a slipper. In our view it makes most sense as a cushioned daily training shoe for shorter easy runs, recovery days and walking, where comfort and durability matter more than speed. The 10mm drop suits heel strikers well. The catch is the price: at an RRP of £180 it asks a lot for what is, at heart, a heavy cushioned cruiser. Watch for a discount and it becomes far easier to recommend. If you want something lighter and quicker from adidas, the Supernova Rise 3 is the more natural daily runner.
The Nike Vomero 18 is Nike's plushest everyday running shoe, a max-cushion daily trainer built to soak up easy miles and protect your legs over the long haul. This is the Vomero finally getting the soft, tall treatment people have wanted for years: a deep, dual-foam midsole that disappears underfoot and keeps feeling fresh deep into a run. It is not fast and it does not pretend to be. At 325g it is a substantial shoe, and the 10mm drop plus generous stack push it firmly into the cushioned-cruiser camp rather than the tempo one. We rate it as a premium easy-day and recovery option, the shoe you reach for the morning after a hard session or for a long, conversational effort. If you want one well-padded daily trainer to carry the bulk of your weekly mileage in comfort, the Vomero 18 makes a strong case. Just do not expect it to feel lively when you push the pace.
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.
