Good to know

  • Designed to take the running game to the next level, the 2nd version of the New Balance FuelCore Sonic features a minimal update. The improvement in the upper of the shoe aims to provide a more precise fit and enhanced comfort.
  • The upper material has been modified, but everything else remains the same. The FuelCore Sonic v2 continue to use the RevLite foam in its midsole and a blown rubber compound in its outer sole.

Based on user reviews, the New Balance FuelCore Sonic v2 runs true to size and true to width, just like the New Balance 990 v4. It offers a comfortable fit from the heel to the forefoot, and the presence of the Boa system facilitates a more secure foot lockdown.

Since it is available in wide sizing for both men’s and women’s versions, wide-footed runners will surely find the shoe snug.

In the outsole of this road running shoe is the lightweight blown rubber compound. It is strategically placed in high-wear areas to give the outer sole durability.

For flexibility, flex grooves are added to the outsole unit. It conforms to the natural bending of the foot as it moves through the gait cycle.

Just like its predecessor, the FuelCore Sonic v2 features the RevLite midsole cushioning which offers responsiveness and long-lasting comfort. As a reliable neutral running shoe, the RevLite foam efficiently absorbs shock and provides flexibility for a smoother ride.

The Synthetic Mesh material on the upper of the shoe has been modified as well. It gives the shoe a fresh, new look but it still keeps the foot cool and dry through the running activity. The mesh material remains light and it wraps the foot snugly and securely. It also has a soft, breathable lining to provide the foot a smooth and comfortable in-shoe feel.

The main highlight of the shoe is the Boa closure system that features a midfoot canopy. This system uses a micro-adjustable dial and durable laces. The Boa system is highly adjustable and the midfoot strap provides a more secure, personalized fit.

The no-sew cleatie construction of the New Balance FuelCore v2 provides the foot a smooth, blister-free coverage.

Lastly, the rear pull-tab helps the users to easily put on and remove the shoe.
