Steiner Sues Puma

Abby Steiner sued Puma and Mercedes-Benz Grand Prix in Massachusetts Superior Court on April 24, 2026, claiming the footwear caused her career-ending injuries.

Summary

Steiner Starts Master’s

She holds the NCAA indoor 200-meter record and U.S. indoor 200- and 300-meter records.
Steiner placed sixth in the 200-meter at the 2024 U.S. Olympic Trials despite lingering foot issues.

History

Historical Context

In 1978 the California Supreme Court, led by Acting Chief Justice Matthew Tobriner, adopted a plaintiff-friendly standard in Barker v. Lull, holding manufacturers liable for design defects. That precedent underpins Abby Steiner’s 2026 lawsuit against Puma and Mercedes-Benz Grand Prix, which seeks damages for alleged foot injuries. The case could extend product-liability law into elite sports sponsorships.
