On Cloud class action lawsuit overview:

  • Who: Plaintiffs Louis Bologna and Patricia Ramirez filed a class action lawsuit against On Inc.
  • Why: Bologna and Ramirez claim On Inc. sells athletic shoes that contain a defect that causes them to squeak.
  • Where: The On Cloud class action lawsuit was filed in Oregon federal court.

A new class action lawsuit alleges On shoes make an embarrassing squeaking noise when worn, which the company allegedly refuses to cover under its warranty.

Plaintiffs Louis Bologna and Patricia Ramirez filed the class action complaint against On Inc. on Oct. 9 in Oregon federal court, alleging violations of state and federal consumer laws.

The complaint claims that On’s shoes, which feature the company’s signature CloudTec technology, emit a loud and persistent squeaking sound with each step, causing embarrassment for wearers.

Bologna and Ramirez argue that the defect is due to the CloudTec technology used in the outsole of On Inc.’s shoes, which is intended to provide cushioned support when wearers land.

Bologna and Ramirez allege that On has been aware of the issue but has failed to address it, leaving consumers to resort to DIY solutions or stop wearing the shoes altogether.

“Though seemingly inconsequential, according to upset consumers publishing their experience, Defendant has refused to cover this defect—which it has been on notice of—under its warranty,” the On Cloud class action lawsuit says.

Bologna and Ramirez want to represent California and New York classes of consumers who purchased On Inc.’s athletic shoes with CloudTec technology during the class period.

On Cloud shoes with defect retail for as much as $180, class action claims

On’s CloudTec technology is designed to provide cushioned support with hexagonal, octagonal and oval-shaped holes on the outsole, the class action lawsuit says. However, the plaintiffs allege that the friction within these holes causes the squeaking noise, which is amplified by moisture trapped under the insole.

Despite the defect, On shoes retail for between $140 and $180, above the national average for running shoes, Bologna and Ramirez say.

The plaintiffs argue that no reasonable consumer would pay such a high price for shoes that require DIY modifications to be wearable.

The class action lawsuit alleges On has refused to cover the defect under its warranty, which does not extend to “normal wear and tear.”

The plaintiffs claim On Inc. is guilty of violating California’s Unfair Competition Law and Consumers Legal Remedies Act and New York General Business Law.

Bologna and Ramirez demand a jury trial and request declaratory and injunctive relief and an award of compensatory, statutory and punitive damages for themselves and all class members.

Early this year, popular shoe maker Crocs was hit with a lawsuit claiming it falsely advertised regular prices and corresponding phantom discounts on products sold through its website.
