The right shoe for: Anyone who wants a lightweight, thin-soled shoe to grip the ground for faster takeoff
Nitrogen occurs in every organism (and many explosives) but isn’t typically found in shoes. That’s what makes New Balance’s powerful FuelCell technology unique. The cushioning material is made up of a nitrogen-injected TPU foam. The goal in using this foam is to provide a snappy sensation and to help you get your feet off the ground faster. In the FuelCell Impulse, that responsive foam is surrounded by Revlite, an EVA-based foam used in speedy shoes like the 890 and 1400.
With its streamlined silhouette and chevron graphic weave, the FuelCell Impulse is also design-forward. The upper fabric has a bootie construction, offering both stability and breathability, with extra tightness around the ankle for support.
That sleek upper construction along with strategic use of rubber on the outsole makes this shoe check in lightweight, as tested at the Runner’s World Shoe Lab. Testers also found that it delivers comfort, stability, and performance. “This is my favorite shoe I have ever tested. The shoe fits like a glove with extreme comfort and flexibility.”
A Springy MidsoleNitrogen is infused into soft, rubberized TPU foam to create two thin inserts (6mm each) in the midsole. Previous FuelCell models used a full-length sheet, but this model is segmented for a more dynamic ride and smooth stride.
The majority of the midsole is made of New Balance’s Revlite for cushioning in the heel and a smooth transition. Thin foam increases responsiveness and speed but also allows for the foot to feel the road.
Lab tests show that the forefoot is quite stiff, but generous toe spring (the upward curve at the front of the shoe) allows it to roll smoothly and not feel so rigid underfoot.
A Light and Grippy OutsoleRubber is used in the heel and forefoot for durability but is stripped away from much of the bottom of the shoe to help keep it lightweight. A large chunk of the midfoot is made up of exposed Revlite foam, but the shoe performs fine, says our test team. “Traction on gravel surfaces was much appreciated for my miles logged with a jogging stroller,” said one tester. “The shoe provided good traction for a shoe with a light base.”
