Diadora Cellula First Run: A Daily Trainer Built for Slow Miles

Introduction

The Diadora Cellula sits alongside the Diadora Gara Carbon in the brand’s road running line, but where the Gara Carbon is built for speed, the Cellula is about slowing things down. It is a daily training companion made for easy runs and long, comfortable mileage where pace is not the priority. After a first run of just over an hour, covering more than eight miles at an easy 8:30-per-mile pace, the early signs are encouraging.

Key Details and Specs

The Cellula is priced at £170 in the UK or $170 in the US, putting it against easy-run focused daily trainers like the Asics Gel Nimbus 25 and 26, New Balance 1080 v13, Hoka Clifton 9, Brooks Glycerin 21, and the Saucony Ride 17. At 276g it is heavier than the New Balance 1080 v13 but lighter than the latest Gel Nimbus.

The stack comes in at 33mm at the heel and 28mm at the forefoot for a 5mm drop. The upper uses nylon mesh and microfiber with a skinny tongue and traditional laces, while the midsole is Diadora’s EVA-based Anima cushioning designed to deliver comfort with a touch of responsiveness. The outsole uses a wear-resistant compound intended to handle a mix of pavement and lighter trails.

Fit and Upper Impressions

Tested in a UK size 8, the usual running shoe size and the same as the Gara Carbon, going true to size appears to pay off here. The Cellula is a naturally accommodating, fairly wide shoe, but even on narrower feet it did not feel overly spacious. It opens up a little in the midfoot without losing lockdown, and toe box room front and sides is very good.

The lacing is a spongy style that avoids putting heavy pressure across the top of the foot. The gusseted tongue was a minor surprise: it is not heavily padded, and it moved slightly out of position during the run. It was more of a nuisance than a real problem. Further back, the heel collar is not heavily padded but offers enough Achilles protection, with no heel rub and no lockdown issues. Overall, true to size should work fine for most runners.

Midsole and Ride Feel

The Cellula feels like quite a dense shoe at first, which is not the most flattering word, but it never ran as heavy or cumbersome. It is not the lightest cushioned easy-run shoe in this class, but it sits in a good place without feeling like too much shoe.

The midsole is a single-density EVA-based foam that is not as plush as similar offerings from New Balance, Saucony, Asics, or Brooks. What it does deliver is effective impact absorption, a nice level of rebound and bounce, and a rocker that is prominent enough to roll you smoothly from heel to toe without being overly aggressive.

Picking the pace up was not awkward either. On quieter, straighter roads the Cellula handled roughly 7:58-per-mile stretches comfortably, which is more than you would expect from a slow-run specialist. The ride sits on the right side of firm and the right side of plush, with enough sink for comfort but plenty of protection over long distances. The naturally wide base also lends the shoe a stable feel, which matters on longer efforts.

Outsole and Durability Questions

In dry conditions on pavement, roads, and a lightly uneven park finish, the outsole performed fine with good grip and reasonably agile movement for a cushioned trainer. The open question is wet-weather durability.

There is not a huge amount of rubber on the outsole: coverage is thin and the shoe is not fully encased in rubber, compared to some other cushioned trainers that offer more protection. Whether it holds up in wetter conditions and over the long term is something that remains to be seen.

Buying Advice

As a cushioned trainer for long runs, slow runs, and easy runs, the Cellula ticks most of the boxes you would want: comfort, a nicely wrapping upper, a stable and slightly bouncy ride, and a smooth rocker. It is not the plushest shoe in its category, so runners who prioritise maximum softness from the Gel Nimbus, Saucony Ride, Brooks Glycerin, or New Balance 1080 class may prefer those alternatives. But if you want impact absorption with a bit more bounce and stability, it is a genuinely appealing option, and it is a shoe that is easy to look forward to running in again.

Conclusion

The Diadora Cellula makes a strong first impression as a comfortable, stable, and slightly bouncy daily trainer for easy mileage. The gusseted tongue is a minor annoyance and outsole durability needs longer-term confirmation, but the early running experience has been mostly impressive and suggests there is real substance behind the growing buzz around Diadora’s road running shoes.
