An Ohio woman is suing the company after developing stress fractures in both hips -- which she blames on the shoes.
Skecher's Shape-ups have a distinctive round sole. They are marketed as toning shoes, the fastest-growing segment of the athletic shoe market.
Toning shoes are meant to help you get in shape as you walk or work. But at least one person says rather than helping them, the shoes hurt them.
Holly Ward, 38, says her routine involves physical therapy and she now has pins in her hips because of injuries she says were caused by wearing Skecher's Shape-ups.
"The extended use of these shoes has injured me catastrophically," Ward told "Good Morning America."
Now, the shoes are being marketed to children as reported on the Today Show.
