Nike fills shoes with tiny beads as the organisation unveils new Joyride Technology to maximise comfort
Nike claims that the Joyride system, which will sit alongside it’s Air and Ultraboost soles, will be more comfortable by using new engineering techniques that allow the bottom of the shoes to be packed out with thousands of little beads.
The beads sit in the sole of the shoe and arrange themselves around the wearer's feet as they run or walk. That allow the shoes to personalise themselves around the shape of the foot and absorb the impact.
Nike has engineered special and separate pods that go under the foot, allowing the foam beads to expand out when the foot presses on them and lets them assemble under the runners' feet, using the pods to ensure that they don't move around too much.
The beads are made of TPE, a material that uses plastic and rubber. Nike claims to have tried 150 materials before finalising the makeup of the beads.
The first shoes featuring the technology – the Nike Joyride Run Flyknit – are available to people in Nike's customer membership before general sale.
