What changed? Less “revolution,” more refinement with intent. New Balance calls it a completely revamped evolution tuned for speed, comfort, and confidence over 26.2. It’s the belief that tiny adjustments - foam feel, roll timing, plate interplay, can make an outsized difference on race day.
The builder himself
Chris Morfesi, Senior Product Manager for Performance Running, is the kind of leader who treats feedback like raw material. As he puts it, “athlete’s insights are integral to how we build footwear.” The v5 isn’t a designer’s decree; it’s a conversation, tested, tweaked, and tested again.
Not a regular testing
Enter Olympic champion and triathlon ace Alex Yee - data in human form. He’s been hands- on with the Boston research lab since 2022, and when he slipped on the v5, he felt “a step on in performance” that elusive blend of responsiveness and natural roll you only notice when it’s suddenly there. “It feels super responsive” and lets him “roll through [his] stride naturally.”
Yee’s verdict didn’t stay theoretical. He debuted the shoe through a full build-up to his first marathon and ran 2:11:08 at the 2025 TCS London Marathon, proof that the lab notes survive contact with the chaos of race day.
The philosophy behind
Great marathon shoes are translators. They take a runner’s intent - hold pace, float the late miles, protect the mind from doubt and render it into motion. SC Elite v5’s update reads like a product poem about margins: strip weight without stripping soul, keep the snap but smooth the landing, chase efficiency without muting joy. Or, to borrow the brand’s framing: the smallest adjustments can change a race.
FuelCell SuperComp Elite v5 landed globally on August 7, 2025. If your A-race sits on the horizon and you want a shoe built by equal parts stopwatch and stethoscope, this is the one that listens and then answers.
