The updated SONIC 4 ACCELERATE is designed to go even faster. We’ve kept our Optivibe™ cushioning to dampen uncomfortable vibrations without sacrificing energy return, so you get a really responsive ride. But, we've reduced material in the forefoot, collar and tongue for an even closer fit. This shoe is ready to pick up the pace, are you?

Reduce vibrations

Optivibe™ cushioning helps limit vibrations with the aim of decreasing muscle fatigue, while continuing to deliver a responsive ride.

Responsive ride

Delivers that bouncy, springy feeling each time you push off the ground.

Featherlight

Now even lighter with a soft, featherweight mesh, collar and tongue, so you feel like you’re flying.
