Salomon SONIC 4 BALANCE

The updated SONIC 4 BALANCE is designed to offer equal parts rebound and cushioning. We've kept our Optivibe™ cushioning to mitigate uncomfortable vibrations without compromising on energy return, so you get a truly responsive ride. Now, this shoe incorporates a fluffier inner bootie and mesh construction and is eager to go further.
