Who should buy the New Balance FuelCell SuperComp Trainer v3 ?
If you’re looking for a training version of the SC Elite v4 that has a similar ride with more durability, the SC Trainer v3 is a great option.
If you’re looking for a stable long run shoe with deep cushioning, the SC Trainer v3 is a great option.
Who should not buy the New Balance FuelCell SuperComp Trainer v3 ?
If you have very wide feet, the narrow fit of the SC Trainer v3 will be uncomfortable for you.
If you want a lightweight, minimal speed trainer with plenty of ground feel, the SC Trainer is not for you.
New Balance FuelCell SuperComp Trainer v3 Introduction
New Balance is very good at classifying their running shoes.
- The Fresh Foam series which consists of shoes such as the 1080, 880, Balos and More is for slow training.
- The FuelCell series which consists of shoes such as the Rebel, SC Elite, SC Trainer, and SC Pacer are for fast training and racing.
- If it has SC (SuperComp) in its name, it has a carbon plate in it.
This makes it easy for runners who are not familiar with New Balance to pick the right shoe.
The FuelCell SuperComp Trainer v3 is a versatile, maximalist shoe for racing or training. Running Warehouse says that the SuperComp Trainer is a super shoe built to deliver race day performance to everyday training.
The SuperComp Trainer is essentially the training companion to the SuperComp Elite, which is New Balance’s flagship long-distance racer.
I put more mileage on last year’s SuperComp Trainer v2 than any other speed trainer I own. I really enjoyed how much deep cushioning it provided and how stable its ride was. l used it for steady-paced and long runs when I was craving a soft ride but I also wanted energy return.
This year’s SC Trainer has a listed weight of 9.6 oz (271 g) for a men’s US 9. My pair weighs 9.4 oz (266 g). This is 0.2 oz (6 g) less than version 2. The stack heights remain the same at 40mm/34mm (6 mm drop) as does its price at $180.
From a design perspective, it’s difficult to tell this year’s FuelCell range apart. From a distance, it’s almost impossible to tell if it’s the New Balance Rebel v4, SC Elite v4 or SC Trainer v3 because they all have the same midsole shape and their colourways follow the same theme.
In the past, this strategy has worked well for brands like Saucony with their Endorphin Speed and Pro.
New Balance FuelCell SuperComp Trainer v3 First Impressions
My first run in the SC Trainer v3 was a 35 kilometre Saturday long run. The first part of that run was at threshold pace while the second part was easy. V3 was comfortable for the entire run: smooth, stable and abundantly cushioned.
The ride was slightly firmer than last year’s version but I don’t mind a firmer ride for a speed trainer because it makes it feel faster. The forefoot also felt stiffer than v2 due to the new forefoot design.
It reminded me of a slightly heavier ASICS Superblast 2 but with a softer ride. The Superblast has more relaxed transitions as it has no plate and its forefoot can flex.
New Balance FuelCell SuperComp Trainer v3 Upper
The SC Trainer v3’s upper feels thinner and more breathable than version 2. It has ventilation holes on the top of the toe-box, and the side panels are thinner for increased air flow.
The gusseted tongue is surprisingly more padded than v2 so there’s more comfort on the top of your feel. A loop on the tongue for the laces to pass through prevents any tongue slide. I find overall foot lockdown to be excellent.
It fits true to size but the forefoot and toe-box are very narrow. Some recommend going up a half size but I like my foot to be over the rocker and not behind it so true to size felt perfect for me. I do not recommend this for wide-footed runners.
New Balance FuelCell SuperComp Trainer v3 Sole Unit
A good training companion should feel very similar to its racing counterpart- if it does, the designers have done a good job. Some of the other training companions feel nothing like their racing companions: the Saucony Endorphin Speed and Nike Zoom Fly come to mind. My first thought when I ran in the SC Trainer v3 was that it feels remarkably similar to the SC Elite v4.
In the midsole of the SC Trainer v3, the FuelCell foam isn’t fully PEBA (like in the SC Elite v4) but it’s a PEBA-EVA blend. This makes it more durable but heavier and not as bouncy. Compared to last year’s version, v3 is firmer, with a more prominent forefoot rocker.
The SC Trainer v3 feels like the fastest version to date. It’s less squishy than its predecessors so when you load it, it doesn’t take as long to decompress.
I enjoy using the SC Trainer v3 for all types of runs but I think its speciality is long runs. I’m currently in the depths of marathon training so I’m doing a lot of medium and long-distance runs.
The SC Trainer v3 is perfect for these types of steady paced training runs because it’s well-cushioned, very stable and efficient. It also has the ability to pick up the pace at the drop of a hat. During recovery and easy runs, it feels alright but not very special.
The central channel that runs underneath the shoe is only in the rearfoot and midfoot. In previous versions, it extended into the forefoot. This means that in v3, there’s more foam in the forefoot- it’s stiffer and the cushioning feels more substantial.
The main reason version 3 is my favourite version to date is that it feels faster. The firmer ride makes it easier to pick up the pace, so it now feels more like a speed trainer and less like a do-it-all daily trainer. Tempo runs, intervals and threshold runs are all more enjoyable in the v3.
Outsole traction is an improvement over version 2. There is more contact with the ground, so it feels grippier. I wore it in the rain once and traction was good. It also feels more stable than previous versions because the outsole design is flatter.
There’s rubber coverage on the high wear areas of the outsole so the SC Trainer v3 won’t wear out prematurely. On my pair, some of the rubber in certain areas has smoothened but that’s normal for my running style.
New Balance FuelCell SuperComp Trainer v3 Conclusions
Version 3 of the SC Trainer is an excellent update and it’s better than v2 in almost every way: it’s lighter, faster and more stable. The upper is also thinner and more breathable. V2 had a softer ride but the increase in midsole firmness is the main reason v3 feels faster.
While its PEBA-EVA blend midsole doesn’t deliver the most energy return on the market, the combination of the plate, the rocker and the foam make it very easy to pick up the pace. The SC Trainer v3 is a fun shoe that I look forward to running in every time.
New Balance could improve it further by reducing its weight. 9.4 oz is heavier than the Endorphin Speed 4, Magic Speed 4, Deviate Nitro 3 and Boston 12.
Version 3 feels less comfortable during easy runs than predecessors and it’s now more speed oriented. It will stay in my rotation as it’s perfect for uptempo long runs. This would be a great budget marathon racer for a midpack runner.
If you can’t get the Superblast 2 due to stock shortages, the SC Trainer v3 is a great alternative and is $20 cheaper.
It’s a little bit heavier but it has more top end speed than the Superblast 2 because of its carbon plate.

New Balance Fresh Foam X 880 v15 Review
4 days ago
Put these through their paces over the last month (180 miles) and I’m thoroughly impressed. The new PEBA blend feels more responsive than v2, especially during tempo runs. Did my weekend long run (18 miles) at marathon pace and they felt fresh throughout. The snappy forefoot really helps maintain pace when fatigue sets in. Compared to my Vaporfly Next%, these are more stable and better suited for training. Used them for several progression runs and a half marathon tune-up race (1:25). The upper breathability is excellent – no hot spots even in humid conditions. While they’re on the heavier side for a plated trainer, the versatility makes up for it.

Been running in these for a few weeks and the tongue keeps sliding to the side during my runs – super annoying! Anyone else dealing with this? Also noticed some wear on the outsole already – hoping it’s not going to be like the v2 where the grip went bad after 200 miles.

Starting my marathon training block and debating between these and the Endorphin Speed 3 for those long Sunday runs. Anyone used both? Also, do these fit like other New Balance shoes? My 1080s are perfect in 10.5 but Fresh Foam X are too snug.

Training for Chicago Marathon and eyeing these for my long runs. Been using Vaporflys but they’re pretty beat up now. Anyone running high mileage in these? Bit worried about the weight for those 20-milers. Also trying to figure out sizing – my feet tend to swell on longer runs so wondering if I should go up half a size?

After 200+ miles in the SuperComp Trainer v3, I’m really impressed with the updates. The new PEBA midsole feels more responsive than v2, especially during tempo runs. I’ve used these for marathon training, including several 20-milers and track workouts. The snappier forefoot is noticeable when picking up the pace – my track intervals are consistently faster than in v2. While not as bouncy as my Vaporfly Next%, they’re perfect for hard training days. The improved breathability is welcome in hot weather. Took these through a recent half marathon PR (1:32) and they felt great throughout. The stability at high speeds is remarkable for a super trainer.

Ugh, really disappointed they made the v3 firmer. Just tried them on at Fleet Feet and they feel nothing like my beloved RC Elites. Spotted the v2s on sale though – might grab those instead since I loved that pillowy soft feel. These prices are getting ridiculous though, nearly had a heart attack when I saw the tag!

Been checking these out for weeks and finally tried them on yesterday. Gotta say, the firmer PEBA foam in v3 is actually pretty sweet – feels more stable than the mushy v2. But man, $180? My Endorphin Speeds were way cheaper and they’re solid. Still sitting here with my credit card trying to justify the splurge…

Been putting these through their paces for about 150 miles now and wow, what an upgrade from the v2! That new PEBA midsole feels way more snappy, which I really notice during my marathon training blocks. Been using them for everything – easy runs, long runs, you name it. Love how responsive the forefoot feels during tempos – way better than the mushy v2. Not quite as poppy as my Vaporflys, but honestly more practical for everyday training. Super breathable upper which is clutch in the summer heat. Only wish they could trim down the weight a bit – my Endorphin Speeds definitely feel lighter. Still, perfect for both recovery days and faster stuff.

I’ve put about 200 miles on these SuperComp Trainer v3s and they’re a significant improvement over the v2. The new PEBA midsole feels noticeably firmer and more responsive, especially during my marathon training tempo runs. I recently used them for a 20-mile long run at marathon pace and they felt fantastic – much more propulsive than my old SC Trainer v2s. The forefoot is indeed snappier thanks to the redesigned outsole. Compared to my Saucony Endorphin Speed 3s, these feel more stable but slightly less bouncy. While heavier than most plated trainers, the extra weight provides better durability. Solid choice for those wanting a more stable plated trainer.

The SuperComp Trainer v3 has become my go-to shoe for tempo runs and long runs with quality segments. Coming from v2, the firmer ride is noticeable but in a good way – it feels more propulsive without losing stability. I’ve done several 16-20 mile training runs and a half marathon race in these. The PEBA foam isn’t as bouncy as Vaporfly but provides better stability for training. The breathable upper is a huge improvement, especially in warm weather. Love how it can handle both easy miles and uptempo work. Compared to the Endorphin Speed 3, these feel more substantial but equally versatile. A great addition to any serious runner’s rotation.

I’ve put about 150 miles on my SuperComp Trainer v3s and they’re exactly what I was hoping for as a faster daily trainer. The new PEBA midsole feels noticeably firmer than v2, which I also owned, making it better suited for tempo runs. I’ve used these for everything from easy 5 milers to a recent 15-mile long run at marathon pace. The snappy forefoot really helps maintain pace in the later miles. While not as bouncy as my Vaporfly Next%, they’re more versatile for training. The upper breathability is excellent – no issues even on humid summer runs. My only minor gripe is they’re a bit heavy compared to other plated trainers like the Endorphin Speed 3. Overall though, these have become my go-to shoes for quality workouts.

The SuperComp Trainer v3 has become my go-to shoe for tempo runs and long training sessions. I’ve logged about 200 miles in them, including several 20-milers during marathon prep. The firmer ride compared to v2 took some getting used to, but now I appreciate the snappy response during uptempo portions. The breathable upper is a huge improvement – no more hot spots like I experienced with v2. Used these for three marathon-pace training runs and they performed beautifully. While not as bouncy as my Adidas Pro 3s, they feel more stable and versatile. Perfect for progressive long runs where you start easy and finish at marathon pace.

The SuperComp Trainer v3 has become my favorite shoe for long training runs. After 300 miles in these, I’m impressed with how the new PEBA midsole maintains its responsiveness. The firmer ride compared to v2 took some getting used to, but now I appreciate how it helps maintain form during those final miles of a 20-miler. Used these for three marathon training cycles and they’ve been fantastic for progression runs and marathon pace work. While not as bouncy as the Vaporfly or Endorphin Pro, they offer better stability for everyday training. The only real drawback is the weight – noticeably heavier than other carbon-plated trainers like the Saucony Endorphin Speed.

Finally got to try on the v3s today and man, that new PEBA foam feels different! Definitely firmer than my v2s but in a good way. Price isn’t too crazy compared to Nike and ASICS right now. Tbh might hold off since my v2s still have plenty of bounce left in them. Anyone else make the switch yet?

I’ve used these for several marathon training runs including a recent 20-miler where they performed excellently. The snappy forefoot really helps maintain pace in the later miles. Compared to my Saucony Endorphin Speed 3, these are more stable but less bouncy. I use them primarily for long runs at marathon pace (around 7:30/mile). While they’re a bit heavy compared to other plated trainers, the trade-off is worth it for the stability. The improved breathability in the upper is also noticeable on warm days.

Hey runners! Looking at the SuperComp Trainer v3 for my fall marathon training block. I’m currently in the 1080v13 (size 8.5) and wondering how these compare size-wise? I’m a pretty average-paced runner (9:00-9:30 miles) and wondering if these might be overkill for me? Also, my ankles tend to get wobbly in softer shoes – anyone coming from the Endorphin Speed 3 can compare the stability?

The SuperComp Trainer v3 has been my primary shoe for the past 3 months of marathon training. Coming from v2, the firmer ride is immediately noticeable – it feels much more suited to uptempo work now. I’ve done several 20+ mile runs and multiple marathon pace workouts in these. The new PEBA blend provides good energy return, though not quite at the level of shoes like the Vaporfly or Adios Pro. The wider platform makes it more stable than most super shoes, which I really appreciate on tired legs. One surprise has been how well it handles recovery runs despite the firmness. Put 300 miles on these preparing for Boston and they’re still going strong. For reference, I’m a 2:45 marathoner. While not perfect, it’s an excellent option for anyone wanting one shoe to handle both training and racing.

Been loving my v2s for the past year but kinda nervous about this update. Anyone else notice the firmer ride? Really liked how soft my current pair feels. Unfortunately my local store doesn’t have them in yet to try. Pretty curious about this new PEBA foam they’re using though!

After putting 150+ miles on the SuperComp Trainer v3, I can confidently say it’s a significant improvement over the v2. The new PEBA midsole feels noticeably firmer and more responsive, especially during my tempo runs. I used these for a recent 18-mile long run at marathon pace and they felt incredibly smooth. The improved breathability in the upper is immediately noticeable – my feet stayed much cooler compared to v2. While not as explosive as my Vaporfly Next%, they’re perfect for those harder training days when you want some pop without destroying your legs. I’ve found them particularly effective for progression runs, starting easy and working down to threshold pace. The outsole durability is also impressive with minimal wear so far.

Hey runners! I’m trying to decide between these and the Endorphin Speed 3 for my marathon training. I slightly overpronate and my current trainers are feeling unstable on those long 15+ mile runs. Anyone had experience with both? Also wondering how the outsole holds up – my v2s started showing wear pretty early.

As a big fan of New Balance FuelCell shoes, I’m curious – how does the SuperComp Trainer V3 compare to the SC Elite v3 in terms of overall responsiveness? I do lots of interval work but want a versatile trainer for long runs too. Which one would you recommend for mixed sessions?
