what is mbt?
MBT (short for Masai Barefoot
Technology) is a feat of Swiss engineering that changes the way you walk to strengthen and engage every muscle in your body. The MBT sneaker is the world's smallest gym, designed to tone muscles, better your balance, perk up your posture, help varicose veins and—as recently reported—get rid of cellulite.

what should i expect and when?
You can pretty much bet on increased energy and balance, and improved posture and muscle tone in the first couple of weeks. After twenty-eight days and several thousand steps, you'll be well on your way to 'bounce a quarter off it abs' and ultra-lithe thighs.
