The updated SONIC 4 CONFIDENCE 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.
