Lie Angle
The angle between the shaft of the club and the ground when the club is soled correctly at address. Standard lie angles vary by club, with irons typically 60–64°.
Lie angle affects where the ball goes: a lie that is too upright (toe of the club elevated) sends the ball left of target for a right-hander; too flat (heel elevated) sends it right. Custom-fit clubs match lie angle to the player's height, arm length, and swing posture.
Simulators don't change lie angle, but a launch monitor with club tracking can reveal whether your lie is causing systematic miss patterns — a clue worth taking to a club fitter.
