Can a $140 shoe really deliver propulsive performance without compromising on daily training comfort? Mike here, and that’s exactly what I set out to discover with the New Balance FuelCell Rebel V4. After 10+ years of testing footwear across every sport imaginable, I was curious if New Balance could back up their claims about this “rebellious” trainer. 8 weeks and 250+ miles later, I’ve got some surprising findings to share.

Design, Build Quality & Real-World Performance
Right out of the box, the Rebel V4 makes a statement. The geometric midsole design isn’t just for show – it’s wider and stacks higher than the previous version, creating this distinctive look that screams “performance trainer.” The engineered mesh upper feels surprisingly substantial for such a lightweight shoe, though I learned early on that this material requires some care.
During my first week of testing, I immediately noticed the FantomFit upper living up to its name. The gusseted tongue with no-sew overlays creates this seamless feel that wraps around your foot without any pressure points. However, after washing my first pair and scrubbing the upper with a brush, I discovered something important: this mesh is prone to abrasion. Little broken fabric filaments appeared all over the right shoe where I’d been aggressive with cleaning. Lesson learned – treat these uppers gently.
The lockdown through the lacing system feels secure without being restrictive. I’m running at 180 lbs with a size 9.5, and the fit is snug but accommodating. However, here’s the first major point every potential buyer needs to know: these run small. Multiple runners in my local running group confirmed this, and I’d strongly recommend going up at least a half size from your normal running shoe size.
FuelCell Foam Performance & Cushioning Response
This is where the Rebel V4 gets interesting. New Balance has reformulated their FuelCell foam for this version, adding more PEBA (the same material used in premium racing shoes) to create what they call a “propulsive feel.” After 250+ miles of testing, I can confirm there’s something special happening underfoot.
My first run immediately felt different. At an easy 7:30 pace, the shoe wants to push you forward – there’s this subtle but noticeable energy return that makes maintaining pace feel effortless. When I picked up the tempo to 6:45 per mile during interval sessions, the foam responded beautifully, providing that springy sensation you expect from higher-end trainers.
I’ll be straight – at my 180 lbs, this cushioning felt fantastic for the first 200 miles. The foam is soft enough to absorb impact but responsive enough to feel fast. I actually set new personal records in both my 1-mile and 5K times while wearing these shoes, despite owning carbon-plated racing shoes like the Nike Vaporfly 3. Sometimes the shoe you wear most often becomes your best performer simply because you’re more comfortable in it.
On-the-Road Performance
I’ve put the Rebel V4 through every scenario I could imagine: easy morning runs, tempo sessions, track intervals, treadmill workouts, and yes, even a few long runs that taught me this shoe’s limitations.
On roads and sidewalks, the geometric midsole design with longitudinal outsole pods provides excellent traction. The 6mm drop feels natural for my midfoot strike pattern, and the rocker geometry helps with smooth transitions. During hot summer runs in 85°F+ weather, the mesh upper breathed well enough to keep my feet comfortable, though I wouldn’t call it the most breathable shoe I’ve tested.
The real test came during my marathon training cycle. While the Rebel V4 excelled at distances up to 15 miles, I hit a wall (literally) during two 17+ mile long runs. I developed significant upper foot pain that I’d never experienced before. After consulting with my running coach and analyzing my form, we suspect the relatively minimal arch support and the shoe’s forward-leaning geometry might contribute to form changes during ultra-long efforts when fatigue sets in.
Does New Balance Deliver on Their Promises?
You know I’m a stickler for details, so when New Balance made bold claims about the Rebel V4’s “propulsive feel” and “rebellious nature,” I had to put each one to the test. Let’s break it down!
First up, they claim “FuelCell foam delivers a propulsive feel to help drive you forward.” In reality, I found this to be about 80% accurate. The first 200 miles felt genuinely propulsive – there’s a noticeable spring that makes tempo runs feel easier. However, after hitting 250+ miles, some of that pop has diminished. It’s still a good trainer, but that initial “wow factor” has mellowed.
Next, the “geometric midsole extends wider and stacks higher” statement is spot-on. Compared to the V3 (which I tested extensively last year), this version definitely feels more substantial underfoot while maintaining that lightweight feel. The wider platform provides better stability during lateral movements and uneven terrain.
As for “fun sublimated graphics” and bringing “an element of fun back into your run,” I’ll give them credit here. The colorways are eye-catching, and there’s something about putting these on that makes you want to run faster. Sometimes the psychological boost is just as important as the physical performance.
Performance in Various Training Conditions
I’ve put the Rebel V4 through its paces in every condition imaginable:
Hot summer runs (85°F+, high humidity): During a brutal August afternoon in Houston, the mesh upper handled the heat reasonably well. Not the most breathable shoe I’ve tested, but adequate for most summer conditions. The foam remained responsive even in heat.
Early morning vs evening runs: 5 AM runs in Denver felt crisp and responsive, while 6 PM sessions in Phoenix showed the shoe maintains its characteristics across temperature ranges. No significant performance differences noted.
Wet conditions: Tested in Seattle drizzle and Dallas thunderstorms. The rubber outsole provides decent grip on wet pavement, though I wouldn’t call it exceptional. The upper isn’t waterproof (nor should it be), but it dries quickly.
Treadmill vs road performance: Honestly, these might be even better on the treadmill. The forward-rolling geometry pairs perfectly with the consistent belt speed, making indoor training sessions feel effortless.
Durability over time: First 200 miles were fantastic. After hitting 250 miles, I noticed the foam compressing slightly and losing some bounce. The upper shows minimal wear except where I made that cleaning mistake. The outsole is wearing evenly with good durability.
My Overall Assessment
Category Breakdown
After 8 weeks of putting the Rebel V4 through everything I could throw at it, I’m giving it 7.8/10 overall. Here’s how it breaks down:
- Design & Aesthetics: 8.5/10 – Looks fantastic and the geometric midsole is eye-catching
- Cushioning Quality: 8.0/10 – Excellent for first 200 miles, then gradually diminishes
- Speed & Responsiveness: 8.5/10 – Genuinely propulsive feel for tempo and speed work
- Durability: 6.5/10 – Upper requires gentle care, foam loses pop around 250 miles
- Value for Money: 7.5/10 – At $140, it’s competitive but not exceptional value
What Other Runners Are Saying
The Rebel V4 works great for my training style, but I’ve heard mixed feedback from the local running community. My buddy John (6’2″, 210 lbs) said “the cushioning felt great initially but bottomed out after heavy training weeks.” Meanwhile, my training partner Sarah (5’6″, 140 lbs) found “the arch a bit too prominent for her flat feet.” However, most of the crew in our tempo group loves them for speed work – it seems like they work best for lighter runners or those doing moderate weekly mileage.
Is It Worth Your Money?
Let’s talk dollars and sense. At $140 for the Rebel V4, here’s my breakdown:
$140 divided by estimated 300-350 mile lifespan = $0.40-$0.47 per mile
Compared to Nike Pegasus 41 ($130): Similar price point, better durability
Compared to Adidas Boston 12 ($140): Equal price, Rebel V4 has better cushioning
Based on delivered features vs promises: 80% delivered × price = decent value proposition
Bottom line: Worth it if you’re logging 25-40 miles per week and want a fun daily trainer that can handle speed work. If you’re a high-mileage runner (50+ miles per week) or need a shoe for 18+ mile long runs, look elsewhere.

Frequently Asked Questions
Based on my testing and what runners need to know, here are the key questions about the Rebel V4:
Q: How does the Rebel V4 fit compared to other popular brands?
A: Compared to Nike, it runs about 0.5 size small. Against Adidas, it’s similar sizing but narrower. If you wear size 9 in Nike Pegasus, you’ll likely need 9.5 in the Rebel V4. The toe box is the main constraint – it’s definitely built for normal to narrow feet.
Q: What’s the break-in period like?
A: Honestly, there isn’t one. Out of the box, expect immediate comfort for runs up to 10 miles. After just 2-3 runs, they’re fully settled in and ready for anything. This was one of the most pleasant surprises during testing.
Q: How long will these shoes realistically last?
A: Light guys (under 150 lbs) report 350-400 miles. Average weight guys (170-185 lbs) like me see 300-350 miles. Heavy runners (200+ lbs) should expect 250-300 miles max. The foam compression is the limiting factor, not outsole wear.
Q: Can I use the Rebel V4 for both easy runs and speed work?
A: Absolutely – this is where it shines. For easy runs at 8:30 pace, it provides excellent cushioning. But when pushing tempo pace at 6:45, the shoe responds with that propulsive feel. It’s genuinely versatile for most training paces.
Q: Are they worth the price compared to the Nike Pegasus 41?
A: The Pegasus offers better durability and wider fit options for $10 less. However, the Rebel V4 has superior speed-day performance and more responsive cushioning. Choose Pegasus for reliability, Rebel V4 for fun factor.
Q: What are the deal-breakers I should know about?
A: The shoe absolutely won’t work if you need wide width, require 18+ mile long run capability, or prefer firm, stable platforms. The biggest limitation is the sizing – if you can’t size up properly, don’t buy them.
Q: Best practices for getting maximum life from these shoes?
A: Rotate with another trainer (don’t use daily), avoid aggressive cleaning of the upper, stick to roads/treadmills rather than trails, and retire them when the foam starts feeling flat rather than pushing to complete outsole wear.
