Lock Step (dance move)

Lock Step refers to any of dance steps which involve the "locking" of the moving foot: the moving foot approaches to the standing foot, crosses in front of or behind it in the direction of the approach, stops close to the standing foot, and the weight is fully transferred on the (previously) moving foot.

The closeness of the feet so that the lower legs of the dancer are "locked" together crossed is the main difference from other cross-steps used, e.g., in the Grapevine, where the moving (crossing) foot travels away from the standing foot and the lower legs are separated. In the Whisk the crossing foot travels around the standing foot, rather than "locks" from the direction of approach.

The term "lock step" or simply "lock" may be applied either to a single "locking" step or to a whole step pattern, e.g., of three steps, such as "step diagonally forward, lock behind, step diagonally forward". The footwork varies depending on the actual dance figure.

Lock steps are popular in Quickstep.
