Do SKECHERS Shape-Ups shoes really work?

A study by the American Council on Exercise shows that SKECHERS Shape-Ups toning shoes do not provide the muscle-toning benefits they claim to deliver. While the shoes' unstable sole causes wearers of the shoes to use different muscles than wearers of traditional sports shoes, they do not improve fitness.

SKECHERS Shape-Ups toning shoes claim to change the wearer's posture, take pressure off overused joints, and burn more calories; however, the ACE study showed that these claims were not true. Another study by the University of Wisconsin-La Crosse also showed no difference in calories burned or in muscle fitness between SKECHERS Shape-Ups wearers and wearers of traditional sports shoes.
