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?
Blown rubber Contagrip®
Super lightweight rubber formula for a cushy feel and ground sensation.
Contagrip® FA combines flat, wide lugs for friction grip on flat, hard surfaces, with a compound that balances durability and adhesion. Ideal for road running.
The midsole is grooved on the top and bottom, increasing flexibility and transition to accompany your stride.
Single layer Mesh
A single layer of Mesh, close to the foot, for maximum feel.
Invisible from the outside, the Sensifit cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around the foot.
Molded EVA sockliner
A molded sockliner that improves comfort by mimicking the foot's natural shape.
