The ACE team tested the Masai Barefoot Technology shoes ($245), Skechers Shape-Ups ($110 – $125) and Reebok EasyTone ($100 – $125) shoes.  The verdict probably won’t surprise you:

Across the board, none of the toning shoes showed statistically significant increases in either exercise response or muscle activation during any of the treadmill trials. There is simply no evidence to support the claims that these shoes will help wearers exercise more intensely, burn more calories or improve muscle strength and tone (Table 1).

“We tested RPE, which is basically how hard one is working, and oxygen consumption, how much oxygen you take in versus being at rest, and caloric expenditure and we found no significant difference between any of the shoes,” says researcher Stephanie Tepper, M.S. “So the toning shoes definitely don’t do more than the regular running shoe.”

As for the muscle-activity testing, the results were strikingly similar. There was no significant difference in EMG levels in any of the muscles tested between the four types of shoes (Figures 1–6).

As the saying goes, if it sounds too good to be true, it usually is…
