New Balance FuelCore Sonic: A good looking misuse of technologyMore photos
The New Balance FuelCore Sonic introduces a BOA tightening system previously found on ski boots. The lack of laces is supposed to make this shoe easier to take on and off and minimize the stress of shoelaces coming undone.
This shoe is the successor to the Vazee Pace v2 and is most comfortably used for short runs and speed runs. The midsole uses RevLite foam for cushioning and a grippy outsole for traction. The upper features no-sew application meant to prevent irritation to the foot.
The addition of the BOA system on a short distance shoe is puzzling to me. One may find that the shoe feels unsecured during sprints and other faster runs.
Looks wise, the shoe is very nice and can fit in with many casual outfits.
At true to size, I find that this shoe fits a tad bit short. Half a size up allows for a snug, comfortable fit. The no-sew upper is comfortable and is good for a wider foot.
The FuelCore Sonic is priced at $140 CAD retail, a pretty average price for running shoes.
There is not much to say about the value of the shoe, but I can say that there are better options in its price range. Buyers are paying for the BOA gimmick if anything.
The FuelCore Sonic has a RevLite midsole which provides a firm responsive ride. This shoe’s midsole and outsole greatly resemble the discontinued Vazee Pace v2, lending hope that the FuelCore Sonic would follow in its footsteps.
Unlike the Pace v2, the shoe does not make me feel light on my feet because I constantly feel as though the shoe is slipping off my foot. The Pace was my go-to when doing tempo runs and I am very disappointed that it was scrapped for the Sonic. I sincerely hope that NB brings back the Pace for a v3.
An unsecured ride
The BOA lacing system detriments the purpose of this shoe. My foot only feels secure when I’m on a light warmup jog; increasing my pace further causes my foot to slip at the heel. I have tried tightening the shoe as far as possible but to no avail.
For this reason, speed work is impossible and I haven’t been able to get my money’s worth out of this shoe. A fair consolation is that the shoe looks nice enough to wear casually, and the midsole is bouncy and comfortable due to the RevLite foam.
Good idea, poor execution
The FuelCore Sonic missed the mark when it came to performance.
The midsole provided a promising base for a great shoe, but the BOA lacing system let it down. On the flip side, the Sonic makes for a great lifestyle shoe as it is easy to slip on and is comfortable enough to walk all day in.
The New Balance FuelCore Sonic is a great looking shoe that had the potential to be a performance- oriented shoe.
It suffers from a misuse of technology that renders it unable to perform how it should. For the price, there are better responsive runners out there.

Fun shoe to run in.
It's a good every day trainer, and picks up to speed really well.
I liked the shoe, but I did not find myself excited grab them off the rack and run in them.
The New Balance FuelCore Sonic has all the makings of a solid trainer for logging big miles, a firm responsive midsole, beefy outsole, and durable upper with a great fit.
- 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 Cleatie construction of the New Balance FuelCore Sonic gives the shoe a lightweight structure and second-skin-like feel.
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 same midsole foam is also used in the FuelCore Sonic 2 running shoe.
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 Cleatie Construction that gives ultimate comfort to runners.
