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.
Features:
Reduce vibrations: Optivibe™ cushioning helps limit vibrations with the aim of decreasing muscle fatigue, while continuing to deliver a responsive ride
Responsive ride: Delivers that bouncy, springy feeling each time you push off the ground
Reassuring comfort: The refined mesh and SensiFit™ construction hug the foot, while a padded collar and tongue keep you comfy
Optivibe™: A combination of foams, one to dampen, one to propel. This was developed to reduce vibration upon foot strike aimed to decrease muscle fatigue without affecting the overall ride
Geometric Decoupling™: Geometric Decoupling™ works with the foot to provide guidance for an effortless and efficient heel-to-toe transition
Soft collar construction: A soft collar improves comfort and creates a more ergonomic feel
