Why a Supertrainer Won This Marathon Shoe Choice

A Tom’s Guide fitness editor is taking the New Balance Supercomp Rebel v1 to a seventh marathon in Frankfurt, rather than a conventional all-out carbon racer. That choice matters because it pushes back on a familiar race-day assumption: the fastest-looking shoe is not always the best shoe for the athlete wearing it. Comfort through the full marathon still wins.

A plate built for living with

The Supercomp Rebel v1 is positioned by New Balance as a fast everyday shoe, or “supertrainer,” rather than its designated race model. Its carbon-infused Pebax plate is more flexible than the plate in the SuperComp Elite v6, and Tom’s Guide makes an important clarification: it is plastic, not carbon. That may sound like a downgrade in the carbon-era marketing arms race. In practice, a less rigid platform can be the smarter call if an aggressive plate creates problems.

That is exactly the case here. The editor reports heel hotspots where the SuperComp Elite v6 plate sits, sometimes ending in a blister, despite having run a personal record in the SuperComp Elite v5. A marathon shoe that feels brilliant for a short hard effort but damages your foot is a bad marathon shoe. Simple as that. The Rebel’s potentially lower price than many carbon racers is useful too, but comfort is the real reason to pay attention.

Fast enough, with wet-road confidence

After more than 100 miles in the shoe, the editor still considers it quick enough for race day. It has also handled a 22-mile run that included miles at race pace. The reported ride is energetic and bouncy, with a better sense of stability than many aggressive carbon-plated options, especially when the pace rises for tempo work or longer race-pace efforts. For runners who want one shoe to cover demanding training and a marathon, that versatility has real value.

Wet-road traction is the other race-specific factor. Frankfurt was expected to be wet, and Tom’s Guide says the Supercomp Rebel v1 retained good grip in its testing. We like that this assessment focuses on a practical detail runners can feel on the day, rather than promising free speed. If conditions are sloppy, secure footing can matter more than a theoretical efficiency edge. It is the same broader lesson behind choosing race footwear carefully, as we found in our [Adidas Adizero Adios Pro 5 review](/en/articles/adidas-adizero-adios-pro-5-review-2026-10-17): fit and how a shoe behaves under your stride come before the spec sheet.

What is missing? The Rebel v1 is not presented as especially stable or supportive at slow paces, so it will not suit every runner or every gait. There is also no promise that it will produce a personal record. We would want more information on sizing, durability and how its cushioning feels late in a marathon before treating it as a universal recommendation.

Verdict: the Supercomp Rebel v1 looks like a compelling race-day option for runners who find stiff carbon racers harsh, unstable or blister-inducing. Against a dedicated carbon shoe, it gives up the purity of the race-only proposition for a more forgiving, adaptable ride. For many marathoners, that is a trade worth making.
