Abby Steiner Sues Puma and Mercedes Over Defective Shoes Ending Her Sprint Career
U.S. track star Abby Steiner filed a lawsuit in Middlesex County Superior Court, Massachusetts, against Puma and Mercedes’ Formula 1 team alleging their running shoes with carbon‑fiber plates and nitrofoam are defective and unsafe, causing injuries that ended her sprint career. The suit names models including Deviate Nitro Elite 2 and 3 and evoSpeed Tokyo Nitro, accuses the defendants of negligent design, manufacturing, and failure to warn, and notes Mercedes’ engineering involvement in track spikes. Steiner wore the shoes with the expectation they were safe and seeks damages under multiple counts, including negligence and breach of warranty, with injuries leading to surgeries by 2025.
