Foot Positions
Regarding Foot Positions, I will quote directly from the Dance Terminology Notebook published by Skippy Blair for the Golden State Dance Teachers Assn.
1st Position Feet Together, heels touching and toes about a thumb's-width apart.
2nd Position Direct Side, feet apart with the same extra distance between toes , rather than the heels - (my comment: about shoulder width apart).
3rd Position Heel to Instep at an angle that allows both knees to face forward then (and if) they are bent.
Extended 3rd Position is the same as 3rd with the feet positioned no farther than shoulder width apart.
4th Position A Walking Step, one foot in front of the other, with a line through the center of the heel and the center of the big toe (walking a straight line or one that curves).
5th Position Toe of one foot placed behind the Heel of the other foot.
Extended 5th Position is the same as 5th with the feet positioned no farther than shoulder width apart.
