  • The New Balance FuelCore Spark is based on the original FuelCore Nergize trainer but sports a slip-on design to make the on-and-off action easier. The upper is made of textured mesh and neoprene to deliver a supportive structure that still promotes movement. The midfoot is adorned with a single strap that keeps the fit snug.
  • The midsole uses the REVLite technology. It is a foam cushioning unit that is lightweight, responsive and hard-wearing. It is crafted to be thick to absorb shock better and keep the foot and joint protected from impact. A removable memory foam insole enhances the comfort offered by the midsole.
  • As for the outsole, rubber is utilized to protect the bottom of the trainer. This component also provides traction on different types of surfaces.

The New Balance FuelCore Spark is engineered to meet the unique needs and dynamics of the female foot. It is available in US sizes 5 to 12 and also in half sizes. For the width, it comes in B - Medium and D - Wide options. The slip-on style makes it convenient to put on, but the midfoot strap keeps the fit snug. Because of the slip-on style, it is crucial to get the correct shoe size.

Rubber protects the underside of the New Balance FuelCore Spark. This material is hard-wearing to keep up with working out on indoor and outdoor surfaces. The rubber is divided into sections which allow the footwear to retain its lightweight nature. The segmented craftsmanship also facilitates natural foot flexibility and motion.

The tread pattern supports multi-directional traction. Under the ball of the foot, the tread pattern is different as it aims to make twists and turns not stressful on the knees.

This New Balance trainer employs the REVLite midsole. This proprietary foam technology is created to be as responsive and durable as other foams that are 30% heavier. Though it is lightweight, its construction was not minimized. Underfoot cushioning is not compromised and stability is retained.

Inside, a removable memory foam amplifies the cushioning offered by the midsole. This full-length component conforms to the shape of the underfoot to deliver maximum support and coverage for extended periods for comfort. It can be easily removed to be replaced by other preferred inserts.

The upper of the New Balance FuelCore Spark sports a low-cut, slip-on construction. The collar is shaped in a way that makes it easier to put on and remove the shoe and promotes movement at the ankle. The forefoot and quarters are made of textured mesh which keeps the inside well-ventilated.

This model does not have a lacing system that would allow customized fit adjustments. What it does have is a midfoot strap that keeps the fit at this area snug. This structure also aims to provide lateral support during dynamic movements.

The tongue and collar are both not padded as the upper is constructed to conform to the shape of the foot for better coverage and support. Neoprene, which has some elastic properties, is used on the collar and rear section to deliver a locked-down fit that is still able to accommodate the foot when it comes in and goes out.
