This model is no longer in production. The closest shoe you can buy today is New Balance FuelCell SuperComp Trainer v3.
New Balance tuned this midsole soft (4/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. At 40 mm of heel stack this sits in max-cushion territory; legs stay fresher on long efforts, but the platform is tall. Combined, the ride reads as snappy at 4/5 responsiveness.
A full-length carbon plate stiffens the forefoot and works with the foam as a lever: it smooths the transition off the toes and cuts the effort of holding fast paces. It also asks for speed — at easy paces a carbon plate feels stiff and does little for you, and it is the main reason super-shoes wear out sooner than trainers.
A 6 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is aggressive: the sole is curved and stiff enough to tip you into the next stride on its own, which saves the calf on long runs but feels strange when you slow right down. Forefoot flex is middle of the road. It is a neutral platform with no built-in correction.
The toe-box is wide, with space for the toes to spread late in long runs. It fits true to size. Expect roughly 250 miles from the outsole, about $0.92 per mile at $230.
