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?
Optivibe™ cushioning helps limit vibrations with the aim of decreasing muscle fatigue, while continuing to deliver a responsive ride.
Delivers that bouncy, springy feeling each time you push off the ground.
Now even lighter with a soft, featherweight mesh, collar and tongue, so you feel like you’re flying.
