The MBT Shoes challenges the muscles to work harder with every step you take. The unique curved sole works by providing instability and makes the muscles of your body more engaged and also helps burn more calories. The MBT Shoes challenges the hard to reach muscles in your legs, but also works the abdominal, back, buttock, and thigh muscles. With every stride, the instability activates the whole body in concert and tones as it stimulates different areas.
