Which foot position is used in the open pas de basque movement?

In Highland dance, the open pas de basque movement requires the dancer to utilize a specific foot position that allows for both balance and fluidity of movement. The position used for this movement is the fourth opposite position (4th opp).

This position is characterized by one foot being placed in front of the other, with the feet turned outwards. It is critical for creating the necessary dynamics needed for the open pas de basque, as this position aids in the execution of the sideways and upward movements that define the step. Furthermore, the use of 4th opp ensures that the dancer can maintain proper alignment and a strong base from which to execute the movement efficiently.

Utilizing other positions, such as third or second, would not provide the same level of freedom or strength needed for the open pas de basque, limiting the dancer's ability to perform the movement effectively. Thus, the fourth opposite position is essential for executing this particular dance step correctly.
