I was curious about the Diadora Cellula 2. Diadora is one of the brands that is not super mainstream in the running world, but definitely underrated. The Diadora Cellula 2 sits firmly in the max cushion daily trainer category, built for runners who want protection, structure, and durability over softness or speed. This second version moves further into the high-stack space and a layered midsole approach, pairing comfort with a noticeably firmer underfoot feel than many shoes in this class.
Rather than the ultra-soft, marshmallow-style cushioning that dominates the premium trainer market right now, the Cellula 2 takes a more controlled approach. The ride is built to handle long stretches of easy running, walking, or standing without feeling unstable. This is not a shoe designed to feel exciting out of the box and really designed for cushion and comfort. To be honest, that is one of my favorite and most important types of shoes.

Before trying the Diadora Cellula 2, I had a few questions:
Is the Diadora Cellula 2 good for long runs?
Yes, as long as those long runs are truly easy. The Cellula 2 is built to handle extended mileage, with enough cushioning and structure to stay comfortable late into a run. It does not respond well to pace changes, so this is not a shoe for long runs that include workouts or fast finishes.
How does the Diadora Cellula 2 compare to the ASICS Gel Nimbus 27?
Both sit in the max cushion daily trainer category, but they feel very different underfoot. The Nimbus 27 leans softer and more forgiving, while the Cellula 2 feels firmer, more structured, and more guided. Runners who dislike overly soft cushioning may prefer the Cellula 2, while those seeking plush comfort will likely gravitate toward the Nimbus.
Is the Diadora Cellula 2 good for walking or standing all day?
Yes. The combination of high stack height, firm midsole, and durable outsole makes the Cellula 2 a strong option for walking and prolonged standing. It feels more supportive than many softer max cushion shoes, which can start to feel unstable over long periods on your feet.
Does the Diadora Cellula 2 have a break-in period?
Yes, and it is noticeable. The midsole and upper both feel firm out of the box, especially in the heel and forefoot. Most runners will need ten to twenty miles before the shoe begins to feel more comfortable. When I first used them, I thought: wow this is a stiff shoe, but it has loosened up to be one of the most comfortable in my rotation.
Is the Diadora Cellula 2 stable?
Although it is listed as a neutral shoe, it provides mild stability through geometry, firmness, and sidewall design. The wide base, structured heel, and long forefoot rocker offer guidance without traditional stability elements, making it suitable for runners who want a stable neutral ride.
Who should skip the Diadora Cellula 2?
Runners looking for a soft, bouncy ride or a shoe that works for speed sessions will likely be disappointed. Those who need a wide toe box or want immediate step-in comfort may also struggle with the fit and break-in.
Now, let’s get into an honest Diadora Cellula 2 shoe review.
Diadora Cellula 2 Fit
The fit of the Cellula 2 will feel familiar if you have worn Diadora before, though it may catch new users off guard. Sizing runs slightly short compared to other brands, and the toe box is more tapered and lower volume than many modern daily trainers. On first wear, the front of the shoe can feel restrictive, particularly over the big toe, due to the structure and overlays used to maintain shape.
That initial snugness does ease with mileage, but the break-in period is real. (Something I rarely say with running shoes, they should feel comfortable out of the box!) Expect the first ten to fifteen miles to feel firmer and more constricted before the upper relaxes slightly. Once broken in, the forefoot opens enough for a standard-width foot, though runners who prefer a wide, rounded toe box may still find this limiting.
Through the midfoot, the shoe feels secure without requiring aggressive lacing. The tongue is thin but well-positioned and gusseted enough to keep everything centered. The heel is generously padded and paired with a firm counter that wraps forward on both sides, adding structure and containment. That firmness may not agree with runners who have sensitive heels, but the padding does a decent job of buffering the stiffness for most.
Breathability lands squarely in the middle of the pack. The upper does not trap heat excessively, nor does it feel especially airy. Internal seams are present, I wouldn’t go sockless. The insole itself is made from a supercritical foam and adds a noticeable layer of step-in comfort, while remaining removable for those who use custom orthotics.
In running shoes, I wear between a women’s size 10-11 wide and have found the size 11 of the Diadora Cellula 2 to fit the best. As mentioned, it took some time to really get comfortable in the shoe but it feels great now that I did. Everything about the upper feels premium.
Diadora Cellula 2 Ride
The first few runs in the Cellula 2 can be surprising if you are expecting a soft, plush feel based on its appearance and stack height. The midsole is firmer than expected, especially in the heel, and the transition from rearfoot to midfoot can feel clunky until the foam begins to settle.
With time, the ride improves. After a few miles, the midsole softens slightly and begins to feel more balanced, particularly in the forefoot. The heel remains on the firmer side throughout, but the lower drop and long forefoot rocker help reduce strain and smooth out toe-off at easy paces. I didn’t realize the Diadora Cellula 2 is only a 5 mm heel to toe drop, but now that I do it makes sense. That’s important to not though, especially if you’ve always used a 12 mm drop.
Where does the Diadora Cellula 2 fit into my rotation? In short, this is an easy run or recovery run shoe. This is not a shoe that responds well to pace changes. The weight is noticeable, and the midsole does not return energy in a way that makes strides or faster running feel natural. Even short pickups feel forced, reinforcing that this shoe belongs strictly in the easy-day category. Where it does shine is in consistency and long, easy miles feel comfortable. I can’t emphasize this enough, it’s a great shoe…just use it for it’s intended use.
Walking and standing are other strong uses for the Cellula 2. The structure, cushioning, and outsole durability make it comfortable for all-day wear, errands, or long periods on your feet, which adds to its versatility beyond running.
Outsole and Durability
Durability is one of the Cellula 2’s strongest attributes. The outsole rubber shows minimal wear even after 100 miles, and traction has been good. I’ve used the Diadora Cellula 2 in inclement weather and on sandy trails with no major issues of sliding.
As far as durability, I expect the Diadora Cellula 2 to last somewhere around 400+ miles. Even after 100 miles, the Diadora Cellula 2 feel almost brand new (if not a little better then brand new).
Diadora Cellula 2 Conclusion:
The Diadora Cellula 2 is a great easy run shoe, but also a great shoe if you are walking, standing or needing an all day shoe. It provides enough cushioning that you can feel like your body is recovering. It’s quickly become one of my favorite easy run/daily run shoes. In my opinion, Diadora is one of the most underrated running shoe brands.
