FOOT FAULT
During the service motion, the server shall not:
1. Change position by walking or running, although slight movements of the feet are permitted; or
2. Touch the baseline or the court with either foot; or
3. Touch the area outside the imaginary extension of the sideline with either
foot; or
4. Touch the imaginary extension of the centre mark with either foot.
If the server breaks this rule it is a “Foot Fault”.
