Some swear by 'toning' footwear, but don't cancel gym membership just yet
Can you wobble your way to buns of steel?
The popularity of "toning" shoes, whose unstable soles require you to work muscles harder to stay balanced, suggests consumers are banking on it.
Sales of toning shoes, which cost from $70 to upward of $200 and have enlisted celebrities like Kim Kardashian and Wayne Gretzky to tout their fitness benefits, soared to $736 million in 2010 from $145 million the year before thanks to the entry of more than a dozen brands into the market, according to market research firm NPD Group.
The ads for many of the shoes, showcasing women with enviably sculpted legs (there are toning shoes for men but the customer base is overwhelmingly female), say that wearing them will help you burn more calories, tone muscles and improve posture. Most manufacturers compare the experience of wearing their shoes to walking on sand.
Foot doctors for years have been prescribing shoes with unstable soles to help patients with foot or ankle arthritis, but can they also get you a few steps closer to firmer thighs?
Peer-reviewed studies on shoes made by Masai Barefoot Technology, pioneers of the rocker-bottom shoes that are beveled at the heel and toe, have found that standing and walking in unstable shoes can strengthen neglected foot muscles and provide some knee and low back pain relief, along with other therapeutic benefits. Studies on FitFlops, which use Microwobbleboard technology in the midsole, have found they reduce foot pressure by an average of 25 percent and can absorb 22 percent more shock in the lower legs.
Whether that translates to a better backside is sketchy.
Skechers, whose Shape-ups have a rocker sole and an "ultrasoft Resamax kinetic wedge" for a squishier cushion, points to a study published last year in the journal Clinical Biomechanics that found that people who walked in MBTs after ankle arthritis surgery burned more calories than controls who walked barefoot or in normal walking shoes. Previous news stories have cited studies funded by Skechers that found people lost more weight and body fat wearing Shape-ups than flat shoes, but those studies were criticized as being poorly controlled (Skechers declined to provide the studies).
Reebok, whose EasyTones use balance-ball-inspired pods and "Moving Air Technology" to create instability, commissioned a study that found electrical activity was 28 percent greater in buttocks muscles and 11 percent greater in calf muscles for wearers of EasyTones versus a regular Reebok walking shoe.

HowStuffWorks "How Muscles Work"
Muscles are one of those things that most of us take completely for granted, but they are incredibly important for two key reasons:
Muscles are the "engine" that your body uses to propel itself. Although they work differently than a car engine or an electric motor , muscles do the same thing -- they turn energy into motion .It would be impossible for you to do anything without your muscles. Absolutely everything that you conceive of with your brain is expressed as muscular motion. The only ways for you to express an idea are with the muscles of your larynx, mouth and tongue (spoken words), with the muscles of your fingers (written words or "talking with your hands") or with the skeletal muscles (body language, dancing, running, building or fighting, to name a few). -->
Because muscles are so crucial to any animal, they are incredibly sophisticated. They are efficient at turning fuel into motion, they are long-lasting, they are self-healing and they are able to grow stronger with practice. They do everything from allowing you to walk to keeping your blood flowing!
When most people think of "muscles," they think about the muscles that we can see. For example, most of us know about the biceps muscles in our arms. But there are three unique kinds of muscle in any mammal's body:
Skeletal muscle is the type of muscle that we can see and feel. When a body builder works out to increase muscle mass, skeletal muscle is what is being exercised . Skeletal muscles attach to the skeleton and come in pairs -- one muscle to move the bone in one direction and another to move it back the other way. These muscles usually contract voluntarily , meaning that you think about contracting them and your nervous system tells them to do so. They can do a short, single contraction ( twitch ) or a long, sustained contraction ( tetanus ).Smooth muscle is found in your digestive system, blood vessels, bladder, airways and, in a female , the uterus . Smooth muscle has the ability to stretch and maintain tension for long periods of time. It contracts involuntarily , meaning that you do not have to think about contracting it because your nervous system controls it automatically.
