Updates to New Balance FuelCore Sonic

  • The New Balance FuelCore Sonic is a road shoe that’s designed to suit the athletic needs of neutral runners. It features an ultra-breathable air mesh upper that helps the runner’s foot to stay comfortable, fresh, and cool, even after several miles of running.
  • It utilizes the Boa Closure System that promotes custom fitting and comfort. It is made up of thin yet durable lace-strands that connect to an adjustable dial. Runners need only to manipulate the dial in order to modify the fit.
  • The Bootie construction of the New Balance FuelCore Sonic gives the shoe a lightweight structure and second-skin-like feel.

New Balance FuelCore Sonic size and fit

When it comes to sizing, the New Balance FuelCore Sonic has a standard running shoe length. This responsive shoe is best for triathletes who undergo daily training. Available widths are D – Medium and 2E – Wide for the men’s version, while the women’s version has B – Medium and D – Wide.


The New Balance FuelCore Sonic has a solid blown rubber outsole that helps runners take control of their movements on the asphalt. This also heightens responsiveness and cushioning because of its soft nature.

Flex grooves are added in order to keep the platform flexible and compliant to the natural bending of the foot as it goes through the gait cycle.


The RevLite midsole of the New Balance FuelCore Sonic is a firm and responsive unit. The RevLite is an innovative foam compound that provides a secure, snug and lightweight cushioning to the shoe. It gives a good amount of protection for the runner’s foot. It provides a more flexible and smoother ride.


The upper of the New Balance FuelCore Sonic utilizes the Boa System. The shoe uses lightweight laces and a micro-adjustable dial. The round dial modifies the fit by tightening or loosening the laces that are connected to the main fabric. One only needs to turn the mechanism in order to get the desired fit.

The low friction lace is designed to aid in a precise and long-lasting fit. This custom fitting allows runners to easily engage and release. The TX4 laces are made of a dyneema-and-polyester mix, which makes them strong yet soft. The Boa L6 dial was made to resist abrasion.

The upper consists of Synthetic Mesh. Its purpose is to wrap the foot snugly and securely. Also, its breathable nature keeps the foot cool and dry.

Textile overlays are purposely added to help the upper fabrics in securing the runner’s foot.

The New Balance FuelCore Sonic has a No-Sew Bootie Construction that gives ultimate comfort to runners.
