The Gel Cumulus 28 is Asics at its most dependable: a cushioned, neutral daily training shoe built to soak up easy miles without asking anything clever of your stride. It is not a max-cushion plush ride and it is not a tempo shoe, it sits in the sensible middle as a do-everything running shoe for the bulk of your week. The 13.3mm drop is high by modern standards, which makes it forgiving and natural if you land on your heel, and the gel cushioning under the rear foot takes the sting out of harder landings. At 252g it is no featherweight, but it carries that weight as stability and longevity rather than dead bulk. We rate it as one of the safest first running shoes you can buy, and a reliable second pair for more experienced runners who want a soft, no-drama trainer for recovery days. If you want more pop, look elsewhere. If you want miles, this is it.
The Mizuno Neo Zen 1 is a soft, springy daily training shoe that shows Mizuno moving on from its old firm reputation. This is a plush, bouncy road running shoe built for the everyday miles that make up most of your week, from easy recovery jogs to steady long runs. At 235g it is genuinely light for a cushioned daily trainer, so it never feels like a chore underfoot. It sits above the Wave Rider as the more premium, more energetic option in Mizuno's line, and at RRP 150 pounds it lands in the same bracket as the plush daily trainers from the big brands. We rate it as a versatile one-shoe answer for a runner who wants comfort without a heavy, dead feel. It is a neutral shoe with a natural 6mm drop, so it rewards a fairly efficient, grounded stride.
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.
