MANCHESTER, England - Former Paralympian Stef Reid has questioned Nike's commitment to diversity over their refusal to sell single shoes to amputee runners even though they use amputee mannequins and runners in promotions.

Reid, a three-times Paralympic medallist in long jump and 200 metres, said she was unable to purchase a single Vaporfly, Nike's top-of-the-line training shoe that retails for about 240 pounds ($300.91) in Britain.
