The Grivet Take
The Rebel v5 trades some of the v4's lean uptempo edge for more cushion and a softer ride, which makes it a better daily long-run option for runners who want PEBA-blended bounce without a plated race shoe. The new midsole reads compliant and bouncy rather than firm and snappy, and the heel collar and tongue padding finally feel finished. The forefoot stays roomy and accommodates medium-to-wide feet, with D and 2E widths offered for men. Two trade-offs to flag: the soft foam dings easily in the high-wear outsole zones, and the lighter, less structured platform asks more of the runner at faster paces than the v4 did. The midfoot instep sits lower than average, which can pinch through the medial midfoot for runners with higher arches. Runners chasing a firm, fast tempo shoe will be happier in the Hoka Mach 5 or Adidas Adizero Evo SL.

Support
Support TypeSupport Type describes how much built-in guidance the shoe has. Neutral shoes do not add support structure. Stability shoes use geometry, rails, firmer foam, or frame designs to create a more guided feel. Motion control shoes are the maximum-support category and are rare in modern running.

Standard platform
How it fits
Length runs true to size for most runners. The forefoot stays roomy, similar to the v4, and the toe box accommodates medium-to-wide feet comfortably without going as foot-shaped as Altra. Midfoot is mixed: the redesigned upper is more padded and more structured than the v4, but the instep height sits lower than average, which can pinch the medial midfoot for runners with higher arches. The base under the midfoot is also narrower, so runners with wide feet sit on top of the platform at faster paces. Heel hold is the most improved area; the new padded collar and stiffer counter lock the rearfoot in place better than any prior Rebel. Offered in D (standard) and 2E (wide); runners needing 4E or wider should consider the New Balance 1080 v14 or 880 v15 instead.
How it feels
The new FuelCell midsole reads soft and bouncy rather than the firmer, snappier feel of the v4. There is a clear forefoot bounce on push-off, and the added 5 mm of midfoot stack smooths transitions on longer efforts. The shoe is highly flexible without a plate; the forefoot bends through the foot rather than rolling on a rigid rocker. This makes the v5 forgiving at easy and moderate paces and capable on longer runs, but the soft foam compresses noticeably at faster paces and loses some of the immediate energy return that runners came to the Rebel line for. Heel landings are smoother than the v4 thanks to the deeper bevel and added stack. Wet-pavement traction is adequate but not strong.

Tech, translated
FuelCell foam in the v5 is a reformulated PEBA-and-EVA blend, softer than the v4 compound and tuned for cushion rather than snap. PEBA adds the bouncy, propulsive feel that runners look for in modern race-style foams; EVA gives the foam enough body to hold up across daily mileage. The shift toward softness is the headline change in this version, and it is noticeable from the first step.
The outsole uses targeted rubber coverage on the forefoot and lateral heel with foam exposed in low-wear zones. Coverage is broader than the v4 in the lateral midfoot but the soft foam itself wears faster than the rubber, so runners who log heavy weekly mileage on rough pavement should expect to see midsole scuffing earlier than on a firmer trainer.
There is no plate. The wide forefoot platform and flexible build do the work of stability and transition; the early forefoot rocker assists on push-off but the foot still does most of the bending.
Frequently asked
Does the New Balance FuelCell Rebel v5 run true to size?
The Rebel v5 runs true to size in length for most runners. The forefoot is roomy and the toe box accommodates medium-to-wide feet comfortably, while the redesigned upper sits more securely than the v4 across the midfoot. The instep is on the lower side, which can pinch the medial midfoot for runners with higher arches. Men's sizes come in D (standard) and 2E (wide); runners needing 4E or wider should consider a different model.
How does the New Balance FuelCell Rebel v5 compare to the Hoka Mach 5?
Both are lightweight daily trainers for runners who want one shoe across easy miles and the occasional faster effort. The Rebel v5 has a softer PEBA-blended FuelCell foam, a more flexible forefoot, and a slightly roomier fit. The Mach 5 has a stronger rocker, a snappier feel at tempo paces, and a more grounded upper. Pick the Rebel v5 for cushion and flexibility; pick the Mach 5 for rocker assistance and a more locked-down feel.
Is the New Balance FuelCell Rebel v5 firm or soft underfoot?
The Rebel v5 lands on the soft, bouncy side rather than firm. The reformulated PEBA-and-EVA FuelCell foam compresses noticeably underfoot and rebounds with a clear forefoot bounce, which is a meaningful change from the firmer v4. It is more cushioned than snappy and is tuned more for daily comfort than uptempo response. Runners looking for a firm, fast feel should look at the Adidas Adizero Evo SL or the Hoka Mach 5 instead.
Is the New Balance FuelCell Rebel v5 good for wide feet?
Men's sizes are offered in D (standard) and 2E (wide), and the D-width toe box itself is on the roomy side, so many medium-to-wide forefeet are comfortable in the standard width. The forefoot opens up enough for toes to splay through long miles. Runners with very wide forefeet who need 4E or wider should look at the New Balance 1080 v14 or 880 v15 instead.
Is the New Balance FuelCell Rebel v5 good for treadmill running?
Yes. The lightweight build, flexible forefoot, and softer FuelCell foam suit the steady cadence of treadmill sessions, especially for easy and long efforts. The rubber outsole grips belt surfaces reliably across most paces. The shoe is more cushioned than the v4, which makes longer treadmill runs more forgiving but does sacrifice some of the snappy responsiveness for faster intervals.
