Versatile and Comfortable Trainer for All Kinds of Runs

"I’ve found the New Balance FuelCell SuperComp Trainer v3 to be an excellent fit for my feet and incredibly comfortable overall. It feels well-cushioned and stable, making it suitable for a wide range of running sessions—from easy, slow-paced runs to tempo workouts. The embedded carbon plate offers a decent level of responsiveness at faster paces, but this shoe seems to focus more on reducing injury risk during training rather than maximizing speed. It strikes a great balance between comfort and performance, making it a solid choice for runners looking for a reliable daily trainer that can handle various types of runs."

It actually works

"New shoes always make me feel fitter and faster, at least initially. The feeling usually disappears after a couple of long runs. This shoe seems different. The enhanced feeling is stronger and lasting longer. Quite remarkable!"

— Riley L. (5/5)

Consistent improvement

"Having ran in the last 2 versions of this shoe, this one has ironed out the issues of its predecessor once again. Upper fit is great, ride is plush but not as soft as the last version. Great training partner for the Elite V4 and with the decent rubber coverage on the outsole I'd expect these to go for a very long time."
