The updated SONIC 4 ACCELERATE is designed to go even faster. We’ve kept our Optivibe™ cushioning to dampen uncomfortable vibrations without sacrificing energy return, so you get a really responsive ride. But, we've reduced material in the forefoot, collar and tongue for an even closer fit. This shoe is ready to pick up the pace, are you?
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.
Now even lighter with a soft, featherweight mesh and collar and tongue, so you feel like you’re flying.
1. Place a sheet of paper on the floor and against a wall.
2. Make sure you are wearing the same socks that you would normally wear with this type of shoe.
3. Wearing these socks, stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
4. Then use a pen to draw a line just in front of your big toe. Repeat for both feet and take the longer distance to determine your size.
5. Using a ruler, measure the distance between the wall and the line you drew to find your size.
