They are part of a 14-piece collection by costume art designer Nikos Floros

Shoes are not the only uncomfortable garment made even more painful by Floros. This corset has also been on show at an art exhibition in Athens

The whole collection took more than five years and 20,000 cans to make! Some pieces took a year on their own

The exhibition is part of a campaign to raise funds for a new opera house and Maria Callas Academy of Lyrical Arts in Athens

Pretty, aren’t they? But theese heels maybe even more uncomfortable than your average pumps – because they’re made from recycled beer and soft-drink cans
