bottom line is if you replace your pivot foot its a travel. Who cares what you call it Euro, spin etc if the offensive player picks up his pivot foot and replaces it then its a travel. Not a hard concept.
While moving:
▬ To pass or shoot for a field goal, the player may jump off a pivot foot and land on one foot or both feet simultaneously. After that, one foot or both feet may be lifted from the floor but neither foot may be returned to the floor before the ball is released from the hand(s)
While moving:
▬ If one foot is touching the floor, that foot becomes the pivot foot.
▬ If both feet are off the floor and the player lands on both feet simultaneous-ly, the moment one foot is lifted, the other foot becomes the pivot foot.
▬ If both feet are off the floor and the player lands on one foot, then that foot becomes the pivot foot. If a player jumps off that foot and comes to a stop landing on both feet simultaneously, then neither foot is a pivot foot.
