Meet Lucky the Humboldt Penguin whose designer sandals make sure he’s always got happy feet.

Keepers at Santa Barbara Zoo, in California, first noticed that Lucky had a limp after he started walking as a hatchling.

The zoo’s vet discovered that his bones were not growing properly, which meant he had been walking on the wrong part of his foot.

If left untreated the problem would leave Lucky susceptible to infections that could prove fatal.

But zoo staff had the bright idea of making a special shoe which would keep Lucky’s foot protected and stop him from limping.

Teva, an outdoor footwear company, agreed to design a penguin-sized water proof sandal and to keep Lucky appropriately booted for the duration of his life.

Dean Noble, a manager at the zoo, said: ‘Lucky is much happier now and he’s stopped limping which is a relief.
