NIKE prosthetic running sole
developed in collaboration with amputee triathlete sarah reinersten and ossur orthopedic innovators, the 'nike sole' is one of the first commercial removable outsoles, designed for use with ossur's 'flex-run' prosthetic foot.

the ‘NIKE sole’ is developed to fit on össur’s ‘flex-run‘ prosthetic running blade, designed for use competitive amputee athletes by NIKE in collaboration with world-record-holding amputee triathlete sarah reinersten and össur orthopedic innovators. recycled materials and nike technology combine in the system that can easily be placed on and removed from a prosthetic blade.

the stacked sole design of the ‘NIKE’ technology features a stretch rubber leash over a rubber waffle outsole, made using nike ‘regrind‘ materials from reused shoes. a polyurethane foam midsole is topped by a moderator composed of a thermal plastic urethane called ‘aeroply’, made of recycled nike air bags. nine nylon plastic tabs serve to lock the sole against the össur flex-run blade.
formerly relying on homemade, makeshift devices for running, sarah reinersten can now use the ‘nike sole’

‘nike sole’ was designed in close collaboration with reinertsen, who tested a series of prototypes and worked with the design team to engineer a secure, high-performing solution. in the past, reinertsen– like other competitive amputee atheletes– relied on simply attaching the outsole of a conventional running shoe to create her own footwear.
the design team was a collaboration among nike, amputee triathlete sarah reinerstee, and össur orthopedics
