We all know what it's like walking on sand. Soft and forgiving but actually quite challenging. Because of the way MBTs work, walking in them is very much like walking on a beach. With the soft heel-sensor and rolling action, your muscles have to work harder than normal and you'll also be using muscles that are usually neglected when walking in typical shoes. The unique MBT design has some remarkable effects. It improves posture, strengthens the back, tones muscles and constantly works the legs, stomach and buttocks. MBTs are not only recommended by orthopedic and physiotherapy specialists around the world, but all the principles of MBT have been verified by the Human Performance Laboratory at the University of Calgary, one of the leading research centers on the body's biomechanical movements. The result of ten years of research and development, MBT is not just a shoe; it is a innovative health and fitness aid that literally works from the ground up. MBT has captured and controlled gravity to improve the overall condition and movements of the body. So every time you wear them, you can be sure you'll feel the positive effects from your body. Each MBT shoe comes with it's own instructional DVD.
