Usually if there is a burning feeling in your undies, then it’s either a suspicious rash or someone has slipped a fire cracker in your pants while you weren’t looking. However, if you want to intentionally feel the burn, donning these fandangled poo catchers will do the job.

Japanese company Wacoal Corporation has launched a range of underwear that burns fat while you wear them.

According to the company, these ‘Cross Walkers’ “will stimulate the muscles of the thighs, and spread it with a natural stride.”

What they probably haven’t noticed is that walking burns fat anyway so anyone who hands over $61 for these burning pants clearly is looking for an easy way out.
