Trust us. These boots aren't really that f-ugly. Besides, after you overcome their aesthetic challenge and hefty-ish price, you'll love how they blend fashion with fitness. How? They're MBTs, a brand of shoe that mimics the effect of walking barefoot on sand or any other unstable surface has on your abs, posture and booty. In other words, they basically work on the same principles as other balancing gear like the Bosu. But since these shoes come in a variety of styles, from sports to professional (like above), you can sneak in extra toning time while you're doing your errands or at work.
