Dutch-born artist and shoemaker Eelko Moorer created "bat boots" that let subway traveller hang upside down!
A shoemaker has created bat-style boots that allow travellers to hang upside down on the London Underground.
Dutch-born Eelko Moorer's footwear can latch on to hand strap rails inside Tube trains.
Mr Moorer, from east London, got his girlfriend Alice Wolff to try the boots out.
"We had a somewhat mixed reaction from other Tube travellers," he said. "Some people were surprised, others liked it and others were appalled."
