nike prosthetic running sole

the 'nike sole', designed for use in conjunction with össur's 'flex-run' prosthetic, offers among the first commercial outsoles for amputee athletes


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.

'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.
