Here are the claims:
- Skechers: “Four clinical studies in the U.S. and Japan show that Shape-ups increase muscle activity and energy consumption over standard fitness shoes!”
- Reebok EasyTone: “It’s the shoe proven to work your hamstrings and calves up to 11 percent harder. And tones your butt up to 28 percent more than regular sneakers just by walking.”
- Masai Barefoot Technology (MBT): “Helping solve knee and back problems, relieve tension in the neck, ease joint pains—and more or less in passing help to tone and shape firm buttocks and thighs. And burning more calories when standing and slow running compared to ordinary shoes.”
Even NFL great Joe Montana has gotten onboard by becoming a spokesperson for Skechers Shape-ups.
Are the claims too good to be true? Each of the above mentioned manufacturers cite their own studies “proving” the benefits that wearers can expect by donning their products.
However, the American Council on Exercise’s chief science officer Cedric Bryant, Ph. D., warns consumers to be cautious of studies sponsored by shoe manufacturers. He warns that these studies may not be peer-reviewed and of questionable design.
