MASAI BAREFOOT TECHNOLOGY (MBT) SHOES
A Swiss engineer studied the perfect posture of Africa's Masai tribesmen then simulated their barefoot stride with these chunky sneakers. With a special, squishy sole that creates a rocking motion and engages the leg, butt and core muscles, MBT shoes also improve posture and balance while minimizing strain on the joints. This fitness footwear is a hit on the Hollywood scene, recently spotted on the feet of celebs like Katherine Heighl, Jennifer Love Hewitt, Gwyneth Paltrow and Heidi Klum.

THE FITFLOP
Called the “flip-flop with a built-in gym,” these sandals feature a similar midsole to the MBT shoes and stimulate butt, hamstring, thigh and calf muscles with each step. FitFlop fans say the cushiony shoes also offer relief from lower back pain, joint aches and pains, and encourage mobility in stiff ankles after just a few days of wearing them. Plus, in a variety of colors and sizes, you can make these flip flops a summer staple by pairing them with everything from sundresses to shorts.

LYTESS MUSCLE TRAINER SNEAKERS
When it comes to buying shoes, you will likely always spring for super-light sneaks over a clunky pair. But these Japanese-designed shoes, which weigh a whopping three pounds each (that is about four times the weight of standard sneakers), might make you reconsider that thought. The extra poundage – courtesy of small metal spheres within the sole – provides a weight-lifting session while you walk, burning up to 300 calories and firming muscles during a half-hour stroll.
Cost: About $150
