The updated SONIC 4 CONFIDENCE W is designed to give you that extra assurance and energy. We’ve kept our Optivibe™ cushioning to dampen uncomfortable vibrations without sacrificing energy return, so you get a really responsive ride. But now with more structured mesh, extra padding and updated SensiFit™ wings, you’ll feel even more confident.
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.
The refined mesh and SensiFit™ construction hug the foot, while a padded collar and tongue keep you comfy.
