Olympic sprinter Abby Steiner has filed a lawsuit against athletic apparel company Puma, alleging that defective running shoes caused injuries that ended her competitive career.

Steiner, who competed for the United States in track and field events, claims in the lawsuit that Puma's running shoes were inadequately tested and posed safety risks to athletes. The legal filing characterizes the footwear as both "defective" and "unsafe."

According to the complaint, Steiner believes Puma failed to conduct proper testing of its running shoe products before releasing them to market. The lawsuit suggests this alleged lack of adequate testing directly contributed to injuries that have forced the sprinter to end her competitive career.

The specific nature and extent of Steiner's injuries have not been detailed in available court documents. Puma has not yet publicly responded to the allegations contained in the lawsuit.

Steiner had been considered a rising star in American sprinting before the injuries that are now the subject of the legal action. The lawsuit seeks damages related to her career-ending injuries and their impact on her athletic prospects.
