"New Balance® FuelCell SuperComp PWR-X v3: When fractions of a second matter on the track, the New Balance FuelCell SuperComp PWR-X v3 is built around one goal - getting you across the finish line faster. This is a sprint spike designed for 60-400m races, and every detail reflects that narrow, focused purpose. FuelCell foam in the midsole creates a propulsive feel underfoot, so the energy you put in comes back to you at toe-off. At 5.9 ounces, it stays out of your way and lets you run.The full-length external carbon fiber plate runs the length of the shoe and includes six built-in pins, giving you the rigidity and traction you need when you're pushing hard out of the blocks or driving through a turn. The ultra-lightweight woven upper keeps things minimal and secure, and the added toe protection is a thoughtful detail for toe drag sprinters who put extra wear on that area. A synthetic/mesh construction and lace-up closure round out the fit, keeping everything locked in when your race demands it.Why Our Fit Experts Love This Shoe""I always point sprinters toward this one when they ask what New Balance has for the track. The carbon plate and six-pin setup give you real grip off the line, and the FuelCell foam actually has some life to it - you're not just running on a stiff board. The toe protection is a nice touch if you're someone who drags during your drive phase."" - Sabrina, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForIf you compete in short to mid-distance track events - anywhere from the 60m to the 400m - the FuelCell SuperComp PWR-X v3 is worth a serious look.
