Burn Fat While Wearing Underwear!?

This sounds too good to be true!
Japanese company Wacoal Corporation has launched a range of underwear that burns fat while you wear them.
The company says the Cross Walkers “will stimulate the muscles of the thighs, and spread it with a natural stride.”
Riiight.
The “miracle” undies sell for $61 and are available for both men and women.
Thoughts???
