New Balance FuelCell Rebel v4 for women: review and price

The New Balance FuelCell Rebel v4 for women is a neutral road running shoe that combines low weight, flexible foam and a plateless construction. It is designed for varied training, particularly uptempo runs, changes of pace and faster sessions.

The women’s version has a listed reference weight of 168 grams and a 6 mm drop. Its launch price was €160. It is an appealing option for runners seeking agility without the rigidity of a racing shoe, although it does not provide the dedicated support of a stability model.

A fast shoe that works for training too

The Rebel v4 sits between a bulkier everyday running shoe and an out-and-out racing shoe. Its FuelCell midsole combines EVA and PEBA, materials used to deliver cushioning and elasticity at a low weight. The foam is paired with a curved shape designed to help the transition from landing to toe-off.

The lack of a plate is important to its design. There is no rigid insert restricting how the shoe bends: its response comes from the foam and the shape of the sole. That makes it an option for runners who prefer a more flexible transition to the pronounced feel of some racing shoes.

During a training week, it could cover a run with a progressive finish, an interval session or a sustained effort. It can also be used in a road race. There is no universal minimum pace at which it becomes worthwhile: what matters more is whether the fit and cushioning feel comfortable for the intended time on your feet.

What the laboratory measurements show

Published laboratory tests provide context for the shoe’s construction. They relate to a reference sample weighing 213 grams, not the advertised women’s weight; measurements can vary by size and version. The comparison helps explain the design, rather than assigning every figure to every women’s pair.

Measured stack height was 28 mm at the heel and 21.5 mm at the forefoot, producing a 6.5 mm drop. That is close to the 6 mm listed commercially. The difference between heel and forefoot is moderate, while the measured stack heights are below the average for the shoes tested.

Midsole hardness measured 23.7 AC against an average of 35.4 AC. A lower number on this scale indicates softer foam in that test. Measured forefoot energy return was 66.8%, compared with an average of 61.5%: this describes the material’s behaviour in the test, not an equivalent improvement in running speed.

The forefoot platform measured 124.7 mm wide, compared with an average of 115.1 mm. That broad base provides more contact area, although it does not turn the shoe into a corrective model. The bending test required 8.1 N, against an average of 15.5 N, consistent with a relatively flexible construction.

Soft foam and a wide base: the change from v3

The fourth generation increases the volume of the midsole and widens the platform compared with its predecessor. This is a meaningful change: there is more surface area underfoot while the design still aims to remain lightweight. The front of the shoe is also more generous in shape than the v3.

For a runner familiar with the previous generation, the change is not just a new foam composition. The wider base and geometry alter how the foot is supported; those who prefer a more direct feel may find that this version offers a more cushioned sensation. Preference between the two cannot be reduced to which one has more material.

The increased width should not be confused with pronation control. The Rebel remains a neutral shoe, without the dedicated support some runners seek in stability models. Pronation alone does not establish that a neutral shoe is unsuitable; fit and individual support needs are what matter.

Who it suits and where it may fall short

Its light weight and flexibility make sense for sessions that combine paces: an easy warm-up followed by faster blocks and a cool-down, for example. A runner who prefers one pair for varied sessions may value that range of uses over a shoe designed exclusively for racing.

It can also be used over longer distances, but the choice depends on how much cushioning and structure feels comfortable as time on the road adds up. For someone who prioritises a firmer platform or more support on long runs, a more structured training shoe may be a better fit.

There is no established body-weight limit beyond which this model becomes unsuitable. Reducing the choice to a number would overlook factors such as run duration, fit and preference for soft foam. However, if you use an orthotic or have been advised to use specific support, check that the two work together before making this your regular pair.

Fit, sizing and upper support

The mesh upper uses FantomFit reinforcements to add structure without bulky overlays. The thin tongue and lightweight design reduce the amount of material around the foot, but also provide less padding under the laces than a more conventional training shoe.

The front offers more room than the previous generation, while the midfoot aims for a more precise hold. A roomy toe box does not necessarily mean the entire shoe is wide: these are different dimensions. When trying it on, check toe room, pressure over the instep and heel movement, particularly with the socks you plan to run in.

To choose a size, measure both feet from heel to longest toe and use the official New Balance size chart to find the corresponding size. Try the shoe on while standing and leave room in front of your toes; if your heel lifts or there is pressure at the sides, changing length alone may not solve the fit.

Outsole, terrain and wear

The outsole has rubber sections and leaves other areas of foam exposed to keep weight down. Its natural environment is roads and urban pavement, not mud or loose gravel. On wet or smooth surfaces, grip can vary with the condition of the ground.

In one laboratory test, outsole wear measured 0.8 mm, against an average of 1.1 mm, under the conditions of that test. It is useful information about the tested material’s resistance, but it cannot be converted into a reliable mileage estimate for every runner.

When deciding whether to replace the pair, accumulated changes are more useful than a fixed date: heavily worn rubber, deteriorated foam, visible distortion or a clear loss of comfort are signs that it deserves a closer look. Uneven wear between the two shoes can also alter how they contact the ground.

Price and differences between women’s and men’s versions

The Rebel v4 launched in 2024 with a recommended price of €160. One published offer listed it at €117.98, but that was a specific promotion and does not establish its current price. As an older generation, its cost and available sizes can vary considerably between retailers.

The clearest difference in the product specifications is reference weight: 168 grams for women and around 212 grams for men. These should not be compared as though they were pairs in the same size. Both versions share a neutral design, FuelCell foam and an advertised 6 mm drop; actual fit should be assessed on the foot in the chosen size.

The final price also depends on details that do not appear in the midsole: delivery costs, exchanges and return conditions. For an online purchase, those terms can make an apparently cheaper offer less convenient if the size does not fit.

Where a plateless shoe fits in a rotation

A carbon plate is not a requirement for racing or fast training. The Rebel v4 presents another option: flexible foam instead of a rigid structure. That difference matters both for comfort and for how each runner perceives the transition.

In a rotation, it can cover days with changes of pace alongside a more stable or more cushioned model for other sessions. It can also be the only pair if its fit and protection meet the intended use. The useful decision is not how many shoes are needed, but what role each pair will actually serve.

How we put this review together: we have not tested these shoes. We wrote it by reading published lab tests, brand information and runners’ opinions.
