NAD Finds Tests to Prove Gym Shoe Performance Claims Insufficient
As part of its routine monitoring program, NAD requested substantiation for certain performance and establishment claims made by Reebok International, Ltd. in print and Internet advertising for its EasyTone women's footwear. NAD inquired regarding the following claims: "It's the shoe proven to work your hamstrings and calves up to 11% harder and tones your butt up to 28% more than regular sneakers just by walking;" "Discover up to 28% more of a workout for your butt. And up to 11% more toning in your hamstrings and calves;" and "Better legs and a better butt with every step." Reebok supplied a study of five subjects who were randomly assigned to wear EasyTone shoes, regular walking shoes, or no shoes on an indoor treadmill at a freely chosen pace for five minutes. The study concluded that EasyTone shoe condition suggest the potential exists for both greater muscle force generation and greater metabolic energy expenditure.
