On Running Unisex Cloudboom Strike 2

Co-created with Elite Distance Athletes to Help You PR on Race Day

The second iteration of the Cloudboom Strike takes speed, energy, and propulsion to the next level. With the debut of new CloudTec Sphere midsole technology, this half and full marathon racing shoe is ready to help you reach any new PR.

This new cushioning system features segmented channels in the midsole, delivering greater flex and rebound with each stride. These precisely engineered channels are composed of an upgraded Helion HF super foam material, which boasts lots of energy return and a 15% lighter design than its predecessor.

Within the layers of this springy super foam, you’ll find a curved carbon Speedboard. This plate is lighter weight and stiffer than previous versions, creating more energy return, stability, and forward momentum than ever before. This updated racing shoe is finished with an open-weave mesh upper, keeping it light and breathable while ensuring a snug, secure, race-ready fit.
