A more affordable plated racer with a firm ride
Quick Answer: On Cloudboom Volt Review: The On Cloudboom Volt is a light, firm road racing shoe for runners who want a plated racing shoe without paying flagship money. It pairs two layers of On’s Helion HF racing foam with a carbon-infused Speedboard, and the upper is cut with more toe room than most race shoes. It is On’s more affordable racing option, with a controlled feel rather than the softer ride of the brand’s premium models. The trade-off is a firmer ride that may suit shorter races better than a full marathon..
The On Cloudboom Volt is the entry point to On’s racing range, and the gap between it and the shoes above it is wide. On’s other carbon racers cost far more, so a plated shoe at about $200 matters more here than it would for most brands.
Cheaper does not mean stripped down. The Volt gets the same family of racing foam and the same style of full-length carbon plate as its expensive siblings. What it gives up is the last slice of softness and bounce, which is where most of the cost in a modern racing shoe goes. The question worth asking is whether a firm, controlled racer suits you better than a springy one.

Pros
- A carbon-infused Speedboard and Helion HF racing foam for a $200 launch price.
- Light on the foot at about 7.4 oz, so it feels like a real race shoe.
- A roomier toe box than most racers, which helps people who usually cannot race in carbon shoes.
- A firm, controlled ride that stays steady when you tire.
- Rubber in the places that wear, so the outsole is not an afterthought.
Cons
- It returns less bounce than On’s pricier racers, so it lacks the springy feel the category is known for.
- The firm ride shows up as tired legs late in a marathon.
- The stiff plate and firm foam make it a poor fit for easy walking or everyday use.
- The foam and thin rubber limit how many miles it will last.
- Some published stack measurements disagree; athletes subject to technical shoe rules should verify event eligibility.
What makes the Volt different from On’s other racers
The Volt is a new model rather than an update, so what matters is where it sits in On’s range. Above it are the Cloudboom Strike and the taller, softer Cloudboom Max, each of which costs considerably more. They all use On’s PEBA-based racing foam. PEBA is a lightweight, springy plastic foam used in almost every fast shoe of the last few years.
Where the Volt differs is how that foam is built. It stacks two layers with a carbon plate between them, and the finished shoe rides firmer and lower than the Strike. The other real change is the upper. On’s racing shoes have usually fit narrowly, and the Volt gives your toes more space. For many runners that matters more than any foam talk, because a racing shoe you cannot wear comfortably for two hours is no use at any price.
Who should buy the Cloudboom Volt
Buy it if you want your first carbon racing shoe and a flagship price was never going to happen. This is the least expensive carbon racer On makes, and nothing about the specification feels like a downgrade: real racing foam, a racing-focused Speedboard and a low weight. For a runner doing two or three races a year, that mix at about $200 is a sensible entry point.
Buy it if you like a firm, precise ride. A light, stiff shoe is a good tool over 5K, 10K and half marathon races, because you are on your feet for a limited time and you want a platform that does not squish when you push. It rewards a quick, tidy stride.
Buy it if racing shoes usually pinch. The roomier toe box makes this one of the more wearable carbon shoes, which is a genuinely rare quality. Runners who gave up on the category because everything felt like a slipper two sizes too small should try it before deciding carbon is not for them.
Who should probably skip it
Skip it if what you want from a carbon shoe is that famous springy push. The Volt is firm and controlled, and if you have run in a top-tier racer you will feel the difference at once. Skip it if you are racing a marathon and you are not a light, efficient runner, because the firm ride gets less forgiving as the miles stack up. And skip it if you hoped to train in it often, since the thin outsole rubber makes that an expensive habit.
These shoes give you more of what the Volt holds back:
- Saucony Endorphin Elite 3: a soft, bouncy carbon racer for runners who want that springy feel over a marathon (check price | read review)
- New Balance FuelCell SuperComp Elite v6: a cushioned, springy racer that, unusually for the category, comes in a wide fitting as well as standard (check price | read review)
- Brooks Hyperion Elite 6: a lively, rolling racer built to stay comfortable across a full marathon rather than just a fast 10K (check price | read review)

Fit: true to size with room for your toes
Take your usual size. The length is accurate, the heel is held firmly with little padding, which is normal for a shoe built for speed, and the midfoot is snug through the laces. What stands out is the front of the shoe. There is more room across the toes and more height over the top of the foot than most racing shoes allow, so toes can spread when you push off and the top of the foot does not feel squeezed.
On sells the men’s Volt in a standard width only. That standard fit is generous for a racer, so some people who normally need a wide shoe may get on with it, but if your feet are truly broad it is worth trying a pair before race week. Sizing up would add length rather than width, so it is not a good fix.
The upper is a thin racing mesh with minimal padding, which is standard at this weight. It breathes well and dries quickly. Step-in feel is firm rather than plush, and the shoe sits lower and more solidly underfoot than the softer racers. As with any race shoe, the lack of padding means your socks matter more than usual.

How the ride feels: firm, low and controlled
Stack height is the depth of foam between your foot and the road. Retailers list the Volt at about 41 mm at the heel and 37 mm at the forefoot, a generous amount by any normal measure. The foam is On’s PEBA-based racing material, which on paper belongs to the same family as far more expensive shoes. In this shoe it comes out firm. Landings feel solid rather than soft, and the small 4 mm drop keeps the ride level and low.
On describes the Volt’s Speedboard as carbon-infused, designed to support a fast rolling transition. It resists bending at the toes and encourages a rolling transition toward push-off, which is what makes a plated shoe feel efficient at speed. The Volt does that cleanly. What it does not do is spring. Compared with the best racers, less energy seems to come back out of the midsole, so the shoe rewards you with precision rather than free speed. Over shorter races that is a fair trade. Over a marathon, the firmness is what your legs will remember.
This is a neutral shoe with no support features, so it does nothing to guide a foot that rolls inward. It is, though, a steady racer. A firm midsole under a full-length plate does not squash sideways, and the low drop keeps your foot closer to level, which should feel reassuring when your form starts to go in the last few miles.

Grip and durability: built for race days
Rubber coverage is thin and placed only where the wear happens, with foam exposed across the rest of the sole. That is normal for a racing shoe and it is a big reason the Volt weighs what it does. Grip on dry roads should be good, and the firm platform gives a consistent contact patch. Treat it as a shoe for races and a handful of key workouts, not for everyday miles. The 300 to 500 mile figure people quote for running shoes does not apply to this category.
Is the Cloudboom Volt good for walking?
It is a poor choice, and that is no criticism of the shoe. The carbon plate keeps the sole stiff from heel to toe, and walking depends on your foot bending through every step. In a shoe that refuses to bend, you rock over the front rather than roll, which feels awkward at walking speed and gets tiring quickly.
The firm midsole also gives little protection on hard floors, and there is no arch support to speak of. The thin outsole would wear down quickly under daily walking too. For standing all day, travel or fitness walking, a dedicated walking shoe makes far more sense, and our guide to the best walking shoes covers good options. Save the Volt for race day.
On Cloudboom Volt Alternatives
If you like the Volt’s idea but want a different balance, these three are worth a look.
Hoka Cielo X1 3.0 is the shoe to try if the Volt feels flat. It is built for marathon racing with a rolling, energetic ride, and it is aggressive enough that some runners find it too much, the opposite problem to the Volt’s (check price | read review).
Asics Metaspeed Sky Tokyo suits runners who like the Volt’s light, precise character and want to push the pace with a longer stride. It costs more and is just as single-minded about racing (check price | read review).
If you want a plated shoe you can also train in, Adidas Adizero Boston 13 makes more sense than any pure racer. It is firm and quick in the same way, with more rubber and structure to survive weekly workouts (check price | read review).
Price and value
On launched the Volt at about $200 in 2026, well below the rest of its racing range, and the specification does not look cheap: racing foam, a carbon-infused Speedboard and a light build. That combination for the money is a real saving rather than a marketing one. You pay for it in feel, because the bounce that makes an expensive racer worth the cost is the thing that has been trimmed here. For a first carbon shoe or a runner who races short, that is an easy trade. For a marathoner chasing a time, the extra money elsewhere buys something real.
Final verdict
Best for: 5K to half marathon racing, a first carbon shoe, runners who find race shoes too narrow and anyone who likes a firm, controlled ride.
Avoid if: you want the springy carbon feeling, you plan a marathon at a fast pace, or you need a shoe for regular training.
Fit: true to size, secure heel, unusually roomy toe area for a racer. Standard width only.
Verdict: On has built an honest racing shoe and priced it sensibly, which counts for a lot in this category. The light weight, the carbon-infused Speedboard and the roomier forefoot make it usable by people the rest of the category ignores. The catch is that it is firm where its rivals are lively, so you get efficiency without the sensation everyone buys these shoes for.

Frequently Asked Questions for On Cloudboom Volt
It depends on the stack figure. World Athletics caps road racing shoes at 40 mm of stack, and retailers list the Volt at about 41 mm at the heel. That does not matter for most club and age-group races, but if you race at a level where shoes are checked, confirm the current figure with On first.
It is On’s name for the stiff plate that runs through the midsole. In the Cloudboom Volt it is full-length carbon fiber, and its job is to stop the shoe bending at the toes so you tip forward over the front in one smooth motion. That is why a carbon shoe feels efficient at speed and awkward at walking pace.
Fewer than a daily trainer, because the outsole rubber is thin and placed sparingly. Racing shoes in general are built for a limited number of important miles. Save it for races and a small number of key workouts and it should see you through a season.
Men’s sizes are listed in a standard width only. The standard fit has more toe room and more depth over the top of the foot than most racing shoes, so some runners who usually need a wide find it workable. If your feet are broad, try before race week.
It is one of the better places to start. The firm platform is more predictable than a soft, bouncy racer, and the price means the experiment costs less. Build up gradually either way, since a stiff sole loads the calves and feet differently from a normal trainer.
PEBA is the plastic family most modern racing foams are made from. It is lighter than the older foams and springs back faster, which is why racing shoes got quicker and more expensive at the same time. On’s version is called Helion HF.
