Welcome to the future of fast. The brand new FuelCell Impulse from New Balance is nitrogen-infused for explosive speed and durable enough to stand up to a summer of hard running.
Fit
The shoe streamlines the classic New Balance-fit into a slightly more race-ready profile. So, it hugs the midfoot and wraps the heel just a little bit more than your average trainer. Testers lauded this fit for tempo runs and interval days, saying the shoe felt secure while also offering ample wiggle room for the forefoot during toe-off.
The seamless upper offers a sockliner-like feel. Not a single tester experienced a blister; the shoe is comfy right out of the box. Plus, the bootie-tongue construction keeps everything in place no matter how fast you run. A major win-win for summer tempos.
