*Joyride is the result of intense, iterative trialing. One hundred and fifty materials were tested before landing on a TPE (a copolymer of plastic and rubber) for the beads.

**Engineering the Pods also helped solve the problem of the beads migrating too much around the foot and becoming uncomfortable. With Pods, Nike designers were able to create a zonal-tuning for each respective iteration of Nike Joyride.

***Beads are dispersed within the pods to match the zonal-tuning that aligns with the performance needs of specific points in your stride. (For example, if there are 8,000 total beads in a running shoe, some 50 percent of the beads would cover the heel strike while 5 percent would offer cushioning at the toe.)
