A Double leg is a move that originated from Capoeira but was incorporated into tricking like many other martial arts moves because of its difficulty and aesthetics. Its Capoeira name is Armada Dupla, which means a double armada. An Armada is the capoeira version of a Reverse Roundhouse kick. The distinguishing feature of this move is the fact that both legs remain together during the take off and execution; its name is derived from this feature. After the take off, the torso stays upright and vertical, but will begin to quickly torque in order to swing the legs around and upwards. At the peak of this move, the body is in the shape of a "V". The legs continue to swing over as the body straightens out for the landing.
In tricking, this move can be done from a run, a step in, a standing position, or from another move in a combo. A standing position and linking it in or at the end of a combo are more difficult due to the height and amount of torque needed. In Capoeira, it can be done from a ginga or from another move in a combo.
A similar move is also performed in snowboarding and inline skating and is referred to as a Misty Flip.
