New Balance FuelCell SuperComp Pacer: First Run Review of a Low-Stack Racing Shoe
A lightweight, low-stack carbon plate racer built for 5k to 10k speed. Here is how it felt on first runs, at easy pace and when pushed hard.
Introduction
The New Balance FuelCell SuperComp Pacer is a new lower-stack carbon plate running shoe positioned alongside rivals like the Nike Streakfly and the Adidas Takumi Sen 8. New Balance markets it for short-distance racing, redesigned for events from the 5k to the half marathon. It sits within a broader SuperComp line that also includes a high-stack plated trainer and a long-distance racer, but the Pacer is clearly the speed-focused, lightweight member of the family.
Pricing is £160 in the UK and $150 in the US. It weighs just 199 grams (7 ounces) in a UK size 9, with an 8 millimeter drop and a heel stack that appears to sit around 28 millimeters. That low, lean profile shapes everything about how this shoe runs, so let’s dig into the details.
Design, Upper and Outsole
The upper is stripped back for racing: a very thin material with large mesh openings across the forefoot, minimal padding around the collar, and nothing on the tongue at all. It feels like a shoe built for summer racing, prioritizing breathability and weight savings over plushness.
The outsole follows the same philosophy. There is a small patch of forefoot rubber that extends right up toward toe-off, plus two thin strips at the heel. The rubber sits almost flush with the exposed foam, which suggests the outsole will wear fairly quickly. This is a racing and fast-training shoe, meant to be used sparingly rather than as a daily trainer.

Inside the midsole, a scooping carbon plate sits between two layers of FuelCell foam. This version of the foam feels firmer to the touch than the foam in shoes like the RC Elite 2 or the Rebel v2, which sets the tone for the whole ride.
Design, Upper and Fit
On foot, opinions on fit varied slightly between testers. One UK size 9 wearer found it true to size with a good amount of toe box space, no midfoot pressure, and a nice lockdown feel, though the laces are a little thin. Thin socks worked best; thicker socks made the fit feel tighter.
Another tester, usually a size 8, took a 8.5 and found the fit glove-like with limited room at the end of the foot, and suggested sizing up half a size if you can. A third tester with a narrow foot loved the tight, streamlined racing fit, comparing it favorably to earlier New Balance shoes known for tight toe boxes. The heel and midfoot lockdown earned consistent praise: excellent, secure, and racy.
The practical takeaway: if you want more room, particularly for longer efforts, consider going up half a size.
Ride Feel: Firmer, Flatter and Faster
This is not a soft, squishy super shoe. The ride is noticeably flatter, firmer and harder than a high-stack carbon racer, sitting somewhere between the older RC Elite 1 and classic racing flats like the 1500, with more protection than either. Ground feel is excellent, and the shoe feels nimble and agile on corners thanks to the low stack.

Interestingly, the shoe still encourages faster running. Even on easy sections, testers reported glancing down to find themselves running quicker than intended, with heart rate staying comfortable. That classic “super shoe” nudge is present, just in a subtler, more direct form than a big-stack racer.
On easy miles, though, opinions diverged. One tester was surprised at how comfortable the shoe felt over nine miles including relaxed sections, while another found steady-paced running genuinely uncomfortable, calling the shoe too lean for anything slower than race pace.
How It Feels at Speed
At pace is where the Pacer comes alive. In road and track testing, the lightness combined with the FuelCell foam made picking up the pace feel effortless, with sprints from 100 meters up to faster 600-meter laps feeling great at around 3:15/km. The shoe feels fast without feeling overtly propulsive; the carbon plate is not obviously noticeable, which is not a bad thing.

Compared with rivals, one tester found it more reminiscent of the Takumi Sen 8: firmer, more direct, more of a true super shoe feel, while the Streakfly leans spongier and more comfort-oriented. On long strides at faster paces, the lack of a higher, springier stack does become noticeable, but for sharp corners and quick direction changes, the low stack makes this a genuinely fun shoe.
Things to Consider Before Buying
The consensus across testers: this is a shoe very much designed for short distances and fast running. Best use cases are 5k and 10k races, track sessions, and interval workouts. There is enough protection that some testers think it could stretch to a half marathon, and the marketing supports that range, but at least one tester capped their personal limit at 10k and would not choose it for a half marathon.
Easy miles are not its purpose. If your priority is a cushioned shoe for steady running, this is not it. If you want a light, snappy, stable weapon for race day and fast sessions, it delivers exactly that.

Buying Advice
Consider the SuperComp Pacer if you race 5k and 10k regularly, do track or interval sessions, or want a lower-stack alternative to big carbon racers that is a bit cheaper, a bit lighter, and noticeably closer to the ground. Size up half a size if you want more toe box room, and pair it with thin socks for the best fit.
Skip it if you want an easy-day trainer or a cushioned half marathon racer. For those roles, a high-stack plated shoe remains the better tool.
Conclusion
The New Balance FuelCell SuperComp Pacer is a lovely, lightweight, snappy racing shoe that rewards speed and punishes patience. It is firm, direct and nimble, with a comfortable enough ride to surprise you on slightly longer runs, but its heart is clearly in 5k and 10k racing. If that matches your goals, it is a very promising addition to a racing rotation.
