Pointe shoe

A pointe shoe is a type of shoe worn by ballet dancers when performing pointe work. Pointe shoes were conceived in response to the desire for dancers to appear weightless and sylph-like and have evolved to enable dancers to dance en pointe (on the tips of their toes) for extended periods of time. They are normally worn by female dancers, though male dancers may wear them for unorthodox roles such as the ugly stepsisters in Cinderella, or in dance companies that feature men dancing as women, such as Les Ballets Trockadero. They are manufactured in a variety of colors, most commonly in shades of light pink.
