New Balance FuelCell SuperComp Trainer v2: review and price

The New Balance FuelCell SuperComp Trainer v2 is a carbon-plated training shoe designed for logging miles on the road. It combines a heavily cushioned midsole with a lower, lighter build than its predecessor, making it particularly well suited to long runs and sustained efforts.

Its launch price was €230, a substantial sum for a shoe that does not need to be saved for race day. Compared with a dedicated marathon racer, its construction is geared more towards training; compared with a conventional daily trainer, it adds a plate and a more elaborate geometry, though that does not guarantee it will be better for every runner.

A plated shoe built for training

The SuperComp Trainer v2 belongs to the category known as supertrainers: shoes that bring elements of racing footwear into a design made for higher-volume training. Here, the recipe combines FuelCell foam, a carbon plate and a tall midsole.

It makes the most sense for long runs, progressive workouts and blocks at marathon pace. It can also be used for a half marathon or marathon, particularly by runners who want a familiar, well-cushioned shoe, although its construction does not pursue the extreme lightness of a dedicated racer.

For short intervals, the midsole’s bulk and the shoe’s weight matter more. The plate allows for changes of pace, but it does not make the shoe especially light for fast repetitions or workouts where a more direct ride is preferable.

Price and key specifications

The model launched in Spain with a reference price of €230. It is a 2023 edition, so availability of sizes, widths and colours may be limited, and current prices can vary between retailers. The launch price places it at the premium end of the market, rather than guaranteeing what it costs today.

Product listings put the weight at around 283 grams for men and 222 grams for women. These are reference figures that change with size; they should not be read as a design difference applicable to every pair. In published laboratory tests, one sample weighed 264 grams, though that figure cannot directly establish the weight of another size.

The stated drop is 6 millimetres. This measures the height difference between heel and forefoot, not the total amount of cushioning. Intended use matters when weighing up the cost: an unplated shoe may be sufficient for easy runs if the distinctive feel of this construction is not a priority.

What changed from the first version

The most visible change is the height. The first SuperComp Trainer had stated measurements of 47 millimetres at the heel and 39 at the forefoot; the second comes down to 40 and 34 millimetres, respectively. It remains a tall shoe, but there is less foam beneath the foot.

New Balance also redesigned the upper and altered the channel underneath. The combination of a lower platform and a revised structure provides a more controlled base than its predecessor, although the cushioning remains soft. Runners who enjoyed the particularly oversized character of the first edition may find that change less appealing.

The reduction in weight is another significant difference, although figures depend on size and measurement method. Comparing two pairs in the same size is more useful than setting a catalogue weight for one version against a laboratory sample of the other.

FuelCell cushioning and the Energy Arc plate

The midsole uses very soft FuelCell foam. Published laboratory tests recorded a hardness of 9.6 HA: a low figure that helps explain how easily the material compresses. For runners who prefer a firm base and a clearer feel for the ground, that softness may be a drawback.

The carbon plate runs the length of the shoe and forms part of Energy Arc, a design that combines the curved plate with an open channel underneath. Plate and foam work together through landing and transition; there is no performance improvement figure that applies to every runner simply because the shoe uses this technology.

The sole has a curve that helps the foot roll towards the toes, but there is no need to deliberately change your landing style to use it. Nor is there a minimum cadence or pace that activates the plate: its value depends on whether the whole shoe feels comfortable and suits the planned sessions.

Stack height and drop: Laboratory measurements

One laboratory measurement put the stack height at 39.3 millimetres at the heel and 30.9 at the forefoot, producing a drop of 8.4 millimetres. That differs from the brand’s stated 6 millimetres; heights can vary according to the measuring points and method used.

The difference matters when comparing specifications, but it does not establish that the shoe requires a particular landing style. In practical terms, it remains a high platform, with plenty of material between foot and ground. Runners moving from a low or firm shoe may notice a substantial change in the way it feels underfoot.

Stability and runner profile

The platform measured in the laboratory was 115.6 millimetres wide at the forefoot and 95.6 at the heel. That width provides a broad landing surface and, together with the lower profile compared with the first version, helps contain some sideways movement.

Even so, this is a neutral shoe, not a model with dedicated corrective support. A wide base does not eliminate compression in soft foam. Runners who need support for pronounced overpronation or have been given individual footwear advice should discuss their choice with the professional who provided it.

Body weight alone does not determine whether the shoe is suitable either. A heavier runner may value the amount of foam but still needs to consider stability and fit; a lighter runner will not necessarily benefit less. The decision is more useful when tied to comfort on landing and the type of training, rather than an arbitrary weight limit.

Fit, width and upper

The second version has a more conventional mesh upper and a redesigned heel collar. The aim is to hold the foot over the platform without relying on the highly minimal fit of some racing shoes. The laboratory measurement around the big toe was 76.4 millimetres, useful for comparing samples measured in the same way, but not enough on its own to determine the right size.

It was sold in standard and wide widths, a relevant option for runners who need more room. Availability depends on the version and retailer. Length and width are separate issues: sizing up to relieve pressure at the sides can also leave too much room at the front or make it harder to secure the heel.

Before buying, it is sensible to check New Balance’s size chart against foot length and assess the fit with your usual running socks. For a long run, the toes need room without the foot sliding inside the shoe. When buying online, pay attention to the exchange and return conditions, particularly when only a few sizes of this edition remain.

Road use, grip and wear

The outsole combines rubber sections with exposed foam around the central channel. Its main surface is road pavement: the rubber layout is designed for roads, not to provide the traction of a trail shoe on mud, loose rock or technical ground.

In laboratory testing, the rubber showed good abrasion resistance, while the toe-box fabric produced a less favourable result. These are tests of specific areas, not a prediction of the lifespan of the whole pair. A runner whose toes wear through fabric may find that area reaches its limit before the outsole shows substantial damage.

Longevity also depends on mileage, surface and landing pattern. There is no reliable number of miles at which the midsole stops working for everyone. Watching for uneven wear, reduced comfort or noticeable changes in the way the shoe feels underfoot is more useful than replacing it solely because it has reached a fixed number.

When a plate makes sense for training

A plate may appeal to runners who want to train in a construction similar to the one they will race in, or who prefer the feel of the whole shoe on long runs and progressive workouts. For easy running, however, it is not a technical requirement: a well-fitting conventional shoe can also do the job.

The v2’s value lies in bringing cushioning, rigidity and a distinctive transition together in one pair. Its premium price is easier to justify when those characteristics are used often than when the plate is the only reason to buy. Technology alone does not demonstrate faster recovery or replace sound training planning.

A training shoe that can race too

For marathon preparation, the SuperComp Trainer v2 can cover both long runs and sustained-pace sessions in one shoe. It also gives runners the option of reaching the start line in familiar footwear, an alternative for those who prefer to prioritise fit and cushioning over the lowest possible weight.

For a competition governed by specific footwear rules, check the applicable regulations and the exact model identification. The stated stack height alone is not enough to establish that a shoe is permitted in every event or category.
