If it sounds to good to be true is usually is and that may be the case with Reebok Easy Tone shoes.
Now the Federal Trade Commission is making the shoemaker pay customers $25 million in reimbursements because of false advertising.
"Any of the toning shoes are made for people probably less active and more or less remain less active, or try to get the most out of their shoes versus the workout," Todd Millard, On The Run store manager said.
And while the shoes are designed to make you unstable, they're more likely to cause injury than tone muscles.
"Sometimes when you make your muscles do things they don't want to do, or you make your feet and legs do things, it can cause issues for you," Millard said.
Millard also said many of his clients come in with problems because of the instability of their shoes.
There are so many designs and colors to choose from, but it's not the design that you're looking for, it's the type of shoe and the fit that's most important.
Because traditional exercise shoes, "are made to protect your feet and protect your legs from any kind of injuries," Millard said.
