'Shoe' is the worst four-letter word of all to the folks at MBT, because traditional shoes stabilize us on flat surfaces, resulting in lazy muscles. The human body was designed to walk barefoot on uneven natural surfaces, and MBT's patented pivot sole mimics this action. Wearing MBTs significantly improves your gait and posture and relieves joint and back pressure. MBT also activates more muscles while you're walking or simply standing. This, in turn, stimulates your metabolism, burns extra calories, and can have a firming effect on your abs, legs and butt. (Is that enough reasons to pick up a pair of MBTs and strut?)
