Diadora Cellula 2 Review: A Solid, No-Drama Max Cushion Daily Trainer

Introduction

The max cushion daily trainer category is brutally competitive right now, and the Diadora Cellula 2 walks straight into it at $180. It sits in the Italian brand’s lineup between the softer Nucleo 2 comfort option and the pricier Atomo Star super trainer, and it arrives with a dual supercritical Anima N2 foam setup, a tall stack, and a promise of high mileage protection with some bounce on top.

After testing it across easy miles and a fartlek-style surge workout, the short version is this: it is a genuinely solid shoe that never gets in your way, but it is heavy, it is not the best at anything, and it faces stiff competition at the same price from the Nike Vomero Plus and the Rad UFO.

Who This Shoe Is For

The Cellula 2 is built as a high mileage, impact-absorbing daily trainer. It suits runners who want maximum protection underfoot, a relaxed and smooth ride, and a shoe that handles easy days, long runs, and casual wear without gimmicks. If you are a bigger runner, or you simply want the most cushioned platform possible for building mileage, that is exactly where this shoe aims.

It is not a speed day shoe, and it is not trying to be. Think of it as a slightly firmer alternative to shoes like the Brooks Ghost Max or a standard-issue comfortable daily trainer, with the benefit of being something different from the big brands.

First Impressions and Specs

Out of the box, the Cellula 2 feels like a substantial, well-built shoe. The rocker geometry looks clean, the support base at the heel is decent, and the overall design is very much in line with what a modern max cushion trainer should look like. Diadora consistently designs its shoes well, and this one is no exception.

The specs raise an eyebrow, though. Our men’s US 10.5 sample measured around 330 g (332 g and 328 g on two checks), with a 44 mm heel stack and an 8 mm drop. That is the same stack height as the original Cellula, which weighed about 303 g in the same size. In other words, the new version added roughly 10 percent weight without adding stack. For context, the Nike Vomero Plus comes in around 316 g, the Nucleo 2 around 292 g, and the Rad UFO around 269 g. The Cellula 2 weighs as much as the heaviest shoes in the category.

The midsole uses a dual foam setup built around the Anima N2 compound, a supercritical formulation. In hand it does not feel especially soft; it is noticeably firmer than the Nucleo 2 despite sharing a foam family name. There is good rubber coverage, the shoe is not very flexible, and nothing about the build feels cheap. It simply feels robust.

Upper and Fit

The step-in experience is refreshingly normal. The upper fits true to size in a men’s US 10.5, with just enough length up front, a toe box that runs a touch snug compared to some rivals, and excellent padding around the heel. There is no lace bite, the laces match the colorway, and nothing about the fit feels off.

One detail worth flagging: the midfoot runs slightly narrower, and there is a small arch bump on the medial side that presses gently against the inside of the foot. It was fine for us, but runners with wider feet may want to take note. The tongue is on the thinner side, though it caused no issues during testing.

The colorway situation is a mixed bag. Our dark grey with deep green and teal accents will not be everyone’s first choice, and the alternative options are not especially inspiring either. The good news is that the shoe’s clean, dad-shoe-friendly look makes it a genuinely viable casual pick, the kind of shoe that works for dog walks, the gym, and airport days as easily as for runs.

Ride and Performance

On the run, three words describe the Cellula 2: smooth, firm, and cushioned. The 8 mm drop is a sweet spot for landing anywhere on the platform, whether you strike with the heel, midfoot, or forefoot. The foam sits in a Goldilocks zone: not squishy soft, but never brick-like, and it seems likely to soften up a little with more miles.

The toe-off is where this shoe quietly earns its keep. There is good bounce and response up front, and the firmer forefoot gives you a real platform to push off of, unlike softer trainers that turn mushy when you pick up the pace. During an 8 x 2 minute surge workout at roughly half marathon effort, the shoe handled itself surprisingly well. It did not offer much natural pop, and strides came out around six-minute pace rather than anything quick, but the big stack never got in the way the way some max cushion shoes can when you push.

Over 10 miles, the shoe actually felt better at the end than at the start. That absence of anything bothersome is a low-key quality that matters in a daily trainer. The protection is top notch, the ride is enjoyable without being exciting, and it passed the workhorse test: it can handle any type of run on the calendar, even if it does not make any of them faster.

Things to Consider Before Buying

The biggest consideration is weight. At roughly 330 g, this is one of the heavier shoes in the category, and the fact that it gained 30 g over a predecessor with the same stack height is genuinely puzzling. The weight is the price of protection, and heavier runners or protection-first buyers may not mind, but runners chasing a lighter, nimbler daily trainer have better options.

Price is the second consideration. At $180, the Cellula 2 sits at the same price as the Nike Vomero Plus, a max cushion shoe that is lighter, established, and one of the most popular releases of the year, and about $20 below the Rad UFO, a more versatile, faster, and considerably lighter super trainer. The Cellula 2 is not a bad shoe by any stretch; it just is not the best at anything in its class.

The third consideration is fit. The slightly narrower midfoot and the medial arch bump could bother wider-footed runners, and the toe box runs a touch snug. Wet-weather traction of the rubber is also unproven, so worth watching if you run on slick pavement.

Buying Advice

If you want one protective, good-looking, well-built shoe for relaxed mileage, weekend long runs, and casual use, the Cellula 2 is a nice pick and earns a B+ grade. It rewards buyers who value durability, stability, and a no-weirdness ride over speed and excitement.

If you are price-sensitive or performance-focused, the competition is tough. The Vomero Plus is the safer crowd-pleaser at the same price, and the Rad UFO is the more versatile pick if you want a daily trainer that can also rip workouts. The Cellula 2 makes the most sense for runners who specifically want a firmer, heavier-duty max cushion alternative to the big brands and like the idea of backing a smaller Italian label.

Conclusion

The Diadora Cellula 2 is a solid, smooth, and protective max cushion daily trainer that does everything asked of it without truly excelling anywhere. Its weight gain over the previous generation is hard to explain, and its $180 price puts it up against some of the best daily shoes on the market. But for the right runner, one who prioritizes impact protection, comfort, and a reliable workhorse over versatility and speed, it is an easy shoe to live with and an easy shoe to like.
