New Balance FuelCell SC Trainer V2 Review: Comfortable, but Is It Fast Enough?

Introduction

The New Balance FuelCell SC Trainer V2 arrives with a clear mission: fix the main complaints about the original. The first version was loved for its bouncy FuelCell foam but criticized for a very high stack, a heavy feel, and limited practicality on everyday roads. V2 goes lower, lighter, and more stable. On paper, that should make it one of the most appealing super trainers available.

After a first run and a handful of follow-up sessions, the picture is mixed. This is a genuinely comfortable shoe for easy miles, but it does not deliver the pace or snap many runners will expect at this price.

What’s New in the V2

The headline change is a significant drop in stack height, from 47 millimeters to 40 millimeters in the heel. That combines with a new, less dense midsole design, making the shoe noticeably lighter than before. The claimed weight is 256 grams (9 ounces) for men in a US size 9.5 equivalent, with a 6 millimeter drop.

The build keeps a full-length carbon plate sitting between two layers of FuelCell foam. In the centre of the midsole there is a hollow channel where the plate flattens with each step and reshapes on toe-off, intended to provide energy return. There is also an updated flat knit upper with reinforced sections for support, and a healthy layer of outsole rubber to protect the foam and add grip. Pricing sits at £210 or $179.99.

Fit and Sizing

Fit is one of the friendlier parts of this shoe. A UK 8 (US 9.5 in New Balance sizing) worked well, with enough room in the toe box and a secure hold around the midfoot and heel. It runs a little roomier than many of New Balance’s tighter racing shoes, so unlike some of the brand’s speed shoes, going half a size up is probably not necessary here.

One caveat came out on longer runs: on a 10-mile effort, one tester felt the big toe touching the end of the shoe, suggesting the shoe may run slightly short. That is worth factoring in if you are between sizes.

Ride Feel: Easy Miles vs Faster Paces

On easy runs, the SC Trainer V2 is genuinely pleasant. It feels smaller and nimbler on the foot than the original, and a 10-mile easy run went by comfortably. As a cushioned daily trainer it holds its own, settling into a relaxed pace and minimizing impact.

The disappointment comes when the pace lifts. At tempo and interval efforts, the ride was described as soft, mushy, and muddy. The transition is not quick, there is little punch off the toes, and the carbon plate does not add much at speed. The shoe leans more on a rocker than on snap. Compared directly with the original, the V2 feels lighter but a bit deader, with the first version offering more bounce and punch despite its bulk. It is also still slightly awkward on cambered pavements, where you can feel knocked off centre.

Who Should Buy It

Runners shopping in this category usually want a training partner for marathon build-ups, capable of tempo sessions at or below marathon pace. For that job, the SC Trainer V2 is a questionable fit. It leans much closer to the comfy, big-stack plated daily trainer end of the spectrum, where comfort and impact protection come first and genuine speed is secondary.

If you want a versatile shoe with real pace in it, alternatives in this space may serve you better. But if you want a comfortable, cushioned trainer with a plate that suits easy and moderate miles, the V2 makes sense, provided the price feels justified to you.

Buying Advice

Buy this shoe if your priority is a comfortable, protective daily trainer and you like the FuelCell ride. Skip it if you are expecting a snappy tempo weapon; the foam and plate simply do not deliver much at faster paces in the current build.

Conclusion

The New Balance FuelCell SC Trainer V2 improves on the original in weight, stack height, and practicality, and it is a comfortable companion for easy miles. But its soft, unresponsive ride at speed makes it hard to recommend unreservedly as a fast super trainer at this price. It is a good shoe that may not be the shoe buyers expect it to be.
