New Balance FuelCell SuperComp Elite v4: complete review

The New Balance FuelCell SuperComp Elite v4 has changed the tone of the brand’s racing range: it no longer pursues pure speed alone, but a more mature mix of bounce, protection, and control. In practice, that places it among the most approachable super shoes on the market for running a marathon or half marathon with less muscular punishment, especially when the legs start to feel it from kilometer 30 onward.

The formula is clear: very soft-feeling Pebax foam, a full-length carbon plate with its own geometry, and an outsole that finally performs well in wet conditions. The result is a high-stack racing shoe, yes, but less radical than its appearance suggests. That has an important consequence: it won’t always be the most explosive option in the group, but it is one of the most usable for a wide range of runners.

A less aggressive and more usable super shoe

New Balance has sharpened the message with this model. Compared with other carbon racers that demand very clean technique and a consistently high pace, the FuelCell SuperComp Elite v4 prioritizes ease of use. They don’t feel nervous or impossible to tame. On the contrary, they convey a kind of tense calm, as if the shoe were working in the background to support your stride without forcing you to operate at the limit all the time.

That more docile character shows especially in long races and extended quality sessions. Instead of pushing the runner toward a knife-edge sensation, the Elite v4 cushions a lot, guides quite well, and lets you hold pace with less mechanical noise. For anyone coming from firmer or more aggressive models, that transition can be almost surprising. For anyone looking for their first serious carbon plate shoe, it is a huge plus.

They are not the fastest in their segment in a straight line, but they are among the best at balancing performance and tolerance. And in a marathon, that balance is worth far more than a few grams of lightness or an exaggerated catapult sensation over the first two kilometers. When endurance comes into play, comfort stops being a bonus and becomes part of performance.

PEBA midsole and a very protected ride

The big leap in this generation is in the midsole. New Balance finally takes a clear step toward a true PEBA foam across the whole platform, keeping the FuelCell name but with behavior quite different from previous generations. The sensation is very soft, very pleasant, and with a response that doesn’t feel hollow or overdone. There is bounce, but not theatrical bounce.

The lab data matches that impression. Impact absorption in the heel reaches 146 SA, a high figure even among road shoes, and energy return in the heel sits at 77.3%. Forefoot performance is also strong, with 114 SA of absorption and 72.7% return. These are numbers that help explain why this shoe feels so protective on long runs and marathons.

The actual midsole height sits close to the World Athletics legal limit. In the lab, it was measured at 38.2 mm in the heel and 28.9 mm in the forefoot, with a real drop of 9.3 mm, quite far from the official 4 mm listed by the brand. Beyond the measurement debate, what matters is the feeling: the ride is highly cushioned, and the shoe invites you to maintain a steady pace without the ground hitting hard.

The consistency of the feel also stands out. There isn’t a dry forefoot and a super-soft heel, as with some rival models; here the behavior is more uniform. That favors both heel strikers and midfoot runners, although the shoe is especially enjoyable when the transition is fluid and the stride moves in and out with a bit of rhythm.

The Energy Arc plate and the role of the rocker

The carbon plate does more than simply stiffen the shoe. New Balance uses its Energy Arc design, with a curved geometry and a structure intended to store and return energy during transition. It is not a standard flat plate, but a more complex solution designed to work alongside the midsole and the front rocker.

That shape explains part of the Elite v4’s behavior. The rear section feels firm and structured, while the whole shoe gives more easily toward the front, where it helps with toe-off. The rocker is not aggressively extreme, but it is enough to guide the foot into a quick exit when running at a fast pace. In a marathon, that keeps the shoe from feeling clumsy or lazy as fatigue starts to build.

Torsional rigidity is high, but longitudinal flexibility is not extreme. That combination helps the shoe preserve stability without fully losing natural feel. In other words: the runner notices the plate, but doesn’t feel the shoe forcing an unnatural rhythm. It’s a subtle difference, but a very useful one for anyone looking to race for many kilometers without a constant sense of punishment.

Wide forefoot and a slightly small fit

One of the traits that most distinguishes this model within its category is the last. Compared with other super shoes with an almost surgical fit, the Elite v4 offers a surprisingly roomy forefoot. The measured width of the front area in the lab was 78.4 mm, above average, and toe-box height also leaves room, at 27.3 mm. For runners with sensitive toes, wide feet, or a tendency to get forefoot blisters, this makes a real difference.

The overall feeling is comfort, not tightness. That doesn’t mean the shoe is wide everywhere: the midfoot holds well and the structure doesn’t get sloppy. But it does avoid that funnel effect so common in more radical racing models. Anyone who races many kilometers knows that when the foot swells, that extra room feels like an open window in a stuffy room.

In length, however, you need to be precise. The most repeated impression is that they run a bit small, roughly half a size below what many runners expect in this category. In New Balance, it is usually more useful to go by centimeters and USA equivalent than by European size. The key is finding enough space in the toe box without sacrificing hold, because the upper doesn’t give much with use.

Very breathable upper, but the heel is the delicate point

The FantomFit upper works well for ventilation and fit, even if it isn’t the friendliest upper on the market. The mesh is thin, breathes well, and doesn’t hold excess moisture. In the lab it achieved a 4 out of 5 breathability score, a solid result for a racing shoe designed for marathons and half marathons, especially in cooler or mild conditions.

The construction is light and visually clean, with few reinforcements and a very minimal look. That helps keep weight down, but it also leaves less room for padding. The tongue is just 1.8 mm thick and isn’t gusseted laterally, which reduces comfort if the laces are tightened too much. It’s far from a disaster, but it is something that requires careful adjustment on the first day.

The biggest caveat, and perhaps the most repeated complaint, is the rear collar. The Achilles area can feel a bit rough at first, especially if you take them straight out for a long run or if you’re sensitive in that region. It doesn’t seem to be a universal problem, but it is a point to watch. In a shoe this expensive and so focused on racing, that detail matters more than it should. Still, it doesn’t ruin the package: it simply calls for a bit of caution during the first few uses.

Traction, rain, and a more serious outsole than before

The outsole is one of the clearest improvements over other generations of the SuperComp family. New Balance has covered more surface with rubber and opted for a geometric design that distributes grip better. Instead of leaving too much of the midsole exposed, it has protected the high-wear zones and created a more practical base for running on different surfaces.

In the SATRA TM144 traction test, the shoe recorded 0.46, a decent figure for asphalt and convincing enough in wet conditions. It doesn’t reach the most aggressive level of some benchmark compounds, but it does provide a level of security that this model lacked before. In practice, that opens the door to racing without fear when the course is damp or when the pavement is a bit slippery.

Wet-grip performance is one of the reasons this model has won over so many runners. The shoe stays composed on wet concrete, crosswalks, and uneven asphalt. In addition, the increased rubber coverage also seems to help durability, even if it adds a few grams to the package. It is a coherent choice for the model’s philosophy: give up some lightness to gain security and useful mileage.

Weight, stability, and the price of versatility

The least flattering figure is the weight. At 232 g in the lab, the Elite v4 doesn’t belong to the lightest super-shoe group. On paper, that may sound like a drawback; on the run, however, the sensation is much better than the number suggests. The weight distribution is well resolved, and the shoe doesn’t feel clumsy or top-heavy at marathon or half-marathon pace.

The explanation lies in the combination of a relatively stable base, very forgiving foam, and an orderly transition. Yes, there are lighter and more radical models. But there are also many that feel more nervous, less stable, or more demanding on technique. In that trade-off, New Balance has chosen the side of the average to heavier runner who wants reliability, especially when the race reaches that phase where the stride starts to lose its shine.

Stability is better than expected for a shoe in this category, even if it isn’t its strongest point. The widened base and midsole sidewalls help, but the soft foam still allows some movement. That means it is not the safest option for someone seeking an absolutely firm platform, but it is one of the most balanced for neutral runners who want a less hostile carbon plate shoe.

Reasonable durability for an expensive racing model

In a shoe that costs around 280 euros, durability matters as much as the ride feel. The good news is that the Elite v4 offers pretty respectable resistance for what you’d expect from a carbon racer. The outsole held up well in wear tests, with only 0.8 mm of damage in the harshest trial, a promising figure for such soft rubber.

The upper, by contrast, doesn’t stand out for exceptional durability, though it wasn’t reasonable to ask for the same longevity as a daily trainer. In the lab it scored a 2 out of 5 for upper durability and a 3 out of 5 for heel padding. Those are normal scores within the segment, where lightness usually comes with some compromises. A runner using them for racing and smart training should find a correct lifespan.

The most interesting point is that the shoe ages with a certain dignity. The extra rubber coverage protects the structure, and the PEBA midsole responds well even in cold temperatures: it only stiffened by 6% after spending time in the lab freezer. That gives an idea of its consistency in variable conditions, something valuable for winter races or cold days when other foams become drier and rougher.

Who it suits and who it falls short for

The FuelCell SuperComp Elite v4 is especially well suited to runners looking for a comfortable, stable, and less aggressive super shoe than average. They work very well for marathon, half marathon, and long quality training sessions too. They are a sensible choice for anyone who prioritizes finishing with good legs rather than just flying through the first kilometers.

They also make sense for medium-weight or even heavier runners who usually feel uncomfortable in models that are too soft or narrow. The roomy forefoot and friendly midsole feel make them an interesting option for feet that need space, support, and a less radical sensation. They are not flashy racing shoes, but a serious tool for competing with less punishment.

They are a little less appealing for those chasing maximum aggressiveness in 5K or 10K races, or for anyone looking for the lightest and most explosive shoe in the category. There are sharper models for that. They may also not win over runners who prefer a very snug fit, a high and enveloping heel, or a dry, very direct response underfoot. The Elite v4 doesn’t want to be a scalpel; it wants to be a racing Swiss Army knife.

A final take on the SuperComp line

Within New Balance’s road evolution, this fourth installment marks a change of era. The brand stops chasing a too-experimental feel and moves toward a more complete, more coherent, and easier-to-recommend proposition. The combination of PEBA, Energy Arc plate, good traction, and more room up front places this model in a very competitive position against rivals with much louder media attention.

Its greatest virtue is that it doesn’t force you to run in only one way. It accepts fast paces, handles long runs, responds with enough dynamism, and doesn’t punish you as much as other carbon models. Its biggest weakness, paradoxically, is the same virtue taken to the extreme: it doesn’t stand out brutally in any single area. But in a marathon, where fatigue, heat, route, terrain, and muscle damage all come together, that may be exactly what turns a good shoe into a very useful one.

The New Balance FuelCell SuperComp Elite v4 is not a super shoe made just to boast about numbers. It is a super shoe built to actually run, for a long time, with an uncommon sense of control in this segment. And in a market that often rewards spectacle over effectiveness, that difference is worth a lot more than it may seem.
