Overview

• A federal class action filed in the U.S. District Court for the District of Oregon names Patricia Ramirez and Louis Bologna as lead plaintiffs.
• The complaint claims Cloudmonster models emit a loud, hard-to-stop squeak with each step, rendering the shoes unwearable for some buyers.
• Plaintiffs say they paid a price premium based on On’s marketing, with one reporting squeaks after three uses and the other after about three months.
• Court filings cite Reddit threads, TikTok videos, online reviews, and DIY fixes as evidence that similar squeaking is widespread.
• The suit alleges the issue was excluded from warranty remedies and that returns were denied; reporters say On did not respond to requests for comment at publication.
