Shoes made from stingrays have gone on sale in time for Christmas.
They're made by top shoe designer Oliver Sweeney, who makes expensive shoes for all sorts of celebrities. And they'll cost a whopping £750.
But animal activists are not happy because they say the shoes could threaten rays, which have very few babies and take ages to grow.
Mr Sweeney is the man who created the shoes worn by the England rugby team when they were off the pitch.
