MBT, Masai Barefoot Technology has developed a new ground-breaking fitness aid that makes walking a new experience. The revolutionary uplifting lever spring mechanism of the MBT sole encourages a whole host of muscles, not just in the foot and leg, to be more dynamic, whether you are walking or standing. MBT shoes improve back posture and increase the body's ability to absorb shocks in all its joints. With MBT, walking more erectly looks good, but in addition it makes for a healthier life style, burns up more calories, improves metabolism, increases blood flow and respiration. Every walk in MBT shoes is like a mini aerobic session. This is why MBT shoes have been described as the smallest gym in the world!
