5-year-old Gets Racing Legs:

Why are these legs so expensive? Why doesn't everyone that needs them don't already have them?
"Ellie May Challis of Little Clacton, Essex, England battled meningitis as an infant. She recovered, but her arms and legs had to be amputated. She has since used normal prosthetic legs which were were painful and slow. Now five years old, Ellie has new carbon framed legs, the kind amputee sprinters use."
Apparently she can really move now.
