The lightweight, responsive training shoe for your fast days. 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?
