- The way the feet and legs should be turned out from the hip joints to give the freedom of movement necessary to perform the steps of classical ballet.
- The balletic stance in which the legs are rotated outward so that the legs (and feet) point in opposite directions. A dancer adopting this position is said to be "turned out." Usage varies, but most people seem to measure the degree of turn-out by the angle between the foot and the mid-saggital plane of the body. The ideal, with both feet in a straight line, is thus 90 degrees of turn-out. Turn-out must begin at the hip; forcing the feet and letting everything else follow puts severe strain on the joints, especially the knees. Source: Vance's Fantastic - BALLET DICTIONARY
