Ballet Careful

Ballerinas are beautiful, but unless you are trained, leave the ballet to the ballerinas. Don't try to stand on your toes barefoot or in street shoes. You can seriously injure yourself. Ballerinas train for years on soft shoes before ever even going up on pointe. Let them do it or go take ballet classes and wait. 

Also, Barbie, drawings, and dolls are wrong. Pointe shoe ribbons do NOT go up to the knee. They are wrapped around the ankle a couple times and tied between the achiles tendon (back of ankle) and the bony knob on the inside of your ankle (side that faces the other ankle). The knot is tucked under the wrapped ribbons so it can't be seen. Strings that go around the whole opening of the shoe pull tight and knot at the front top of the shoe and tuck inside the shoe. Elastics are sewn in that go over the tarsals (place between top of foot and ankle) that help keep the shoe on the foot. The box can be made of several different materials depending on the brand, and type. This provides a hard flat tip to stand on. The vamp extends from the box along the sides providing support for the toes and end of the foot. On the bottom is a shank. It is generally pretty stiff and provides support as well. Pointe shoes are often more of a light tanish pink or light pink.
