Skechers USA Inc. was ordered to pay $40 million in a settlement involving false claims that its Shape-ups shoes would help people lose weight and strengthen their butt, leg and stomach muscles.

The settlement involves the Resistance Runner, Toners and Tone-Up shoes.

Consumers who bought the shoes will be eligible for refunds.

The Federal Trade Commission says Skechers falsely represented that clinical studies backed up the company's claims about its toning shoes....tisk...tisk....tisk.

The shoes have been endorsed by the likes of Kim Kardashian and Brooke Burke.

Skechers disputes the charges and is pursuing additional studies.
