Pointe shoes are normally only worn by female ballet dancers. Male dancers may wear them for a comic effect in unorthodox roles such as the Ugly Stepsisters in "Cinderella", or Bottom in "A Midsummer Night's Dream". The all-male dance troupe Les Ballets Trockadero de Monte Carlo have dance programs with choreography entirely on pointe. This is one element of spectacle for the audience to demonstrate how the physical demands of classical ballet combine the artistic and the athletic.
