Overview
The updated SONIC 4 BALANCE W is designed to be as springy as it is cushioned. We’ve kept our Optivibe™ cushioning to dampen uncomfortable vibrations without sacrificing energy return, so you get a really responsive ride. Now with a softer mesh and inner booty construction, this shoe is revving to go the extra mile.
