Woman pranks boyfriend by turning his favourite trainers into monster feet

A woman who was sick of her boyfriend's smelly gym shoes decided to prank him by transforming them into monster feet.

The amusing clip, which was filmed in the UK on Thursday, shows the woman spraying expanding foam all over his favourite trainers to turn them into the massive feet.

She then paints them a monstrous shade of green.

He boyfriend is pretty surprised when he sees his new enormous shoes but plays along with the joke and even agrees to give them a whirl at the gym.
