Running Shoes Lake Worth FL

Every athlete knows what an important difference the right shoes can make in their performance.  But can certain shoes get you in shape just by wearing them?  That's the claim manufacturers of toning shoes like Sketcher's Shape-ups®, Reeboks' Easy Tones®, and MBT® (Masai Barefoot Technology) are making.  But is the claim true?  We've separated fact from fiction about the latest trend in footwear.

What are toning shoes?  Toning shoes are athletic shoes that have a rounded sole or extra cushioning to create an unstable walking surface that alters the wearer's normal walking gait.  This instability is what manufacturers claim is the key to their success.

Manufacturers say their claims are backed by clinical studies.  They don't mention however, that these "clinical studies" were designed and conducted by their own companies and were not peer-reviewed, which means they could prove any claims they wanted. 

The American Council on Exercise (ACE) suspected these shoes were too good to be true so they conducted their own studies. ACE researchers had 12 physically active women walk for five minutes on a treadmill a dozen times wearing regular athletic shoes and three popular brands of toning shoes.  They randomized the shoe order and tested each subject's oxygen consumption, heart rate, ratings of perceived exertion and caloric expenditure.  Then they recruited another group of 12 physically active women and performed a similar battery of treadmill tests using the same four brands of shoes.  This time they used electromyography to record muscle activity in the women's calves, quads, hamstrings, buttocks, back and abs.

What were their results?  The ACE researchers found no significant difference between exercise response or muscle activation and no evidence to support the claims that toning shoes help people who wear them exercise more intensely, burn more calories or improve muscle strength and tone.
