Perfect for hard accelerations, the New Balance FuelCell SuperComp Trainer v3 provides the responsiveness and stability needed for your interval and tempo workouts. Make the most of your fast runs with the unmatched support of the New Balance FuelCell SuperComp Trainer v3. Midsole PEBA foam, a thermoplastic elastomer made from polyether block amide, forms the midsole of this shoe. With its unique properties, PEBA foam has a high energy return. Compared to TPU foam, this foam is considerably lighter, offers better energy return and maintains its performance at all temperatures. The carbon plate has a unique geometry that is also called Energy Arc technology. Between the foam lies a carbon plate that is deformed in two directions. This is an even thinner carbon plate to save weight. A large recess can be seen in the bottom layer, which allows the plate to spring in and out. This is the optimal combination of soft cushioning and maximum energy return. Upper The FantomFit upper is designed to provide ultralight support and fit. FantomFit is made by fusing two thin materials together without sewing. The heel counter is reinforced and provides a surprising amount of support compared to other racing shoes. The tongue is thin, allowing your feet to breathe. Outsole The rubber outsole provides good grip and traction while running.
