After her birth, the piglet refused to join her brothers and sisters as they splashed in the muck because she suffers with mysophobia - a fear of dirt.
But now the pig has overcome her fears with a pair of green boots made of rubber - which have been created with no footwell so that her trotters slip straight in.
Former pig farmers Debbie and Andrew Keeble, who run a farm near Bedale North Yorkshire, were initially baffled by their piglets behaviour.
Debbie Keeble, 40, said: "It was the strangest thing. When the batch ventured away from their mother, Cinders just stood at the edge of her sty shaking while the others explored.
"We thought it was just that she didn't want to leave the sty or the sow but we soon noticed if we moved them to where there wasn't any mud, she happily left it and roamed around without any nonsense.
Her husband, Andrew, 42, added: "We scratched our heads a bit but then we thought, we wouldn't go in the mud bare-footed, so why not try some wellies?"
Cinderella has now been chosen to front a campaign by the couple to support the plight of pig farmers.
