Some tests to identify which foot you should put forward in board sports (regular vs goofy stance)
Here are ways to help you decide which foot to put in the forward in your wakeboard, surfboard, skateboard,etc.
The Falling Test
Stand with your feet together and close your eyes. Ask someone to gently push you forward from behind. Which ever foot goes forward first to catch your balance is the one you should try putting in the forward wakeboard binding or slalom water ski binding. Right foot forward is considered “goofy footed.”
This is most effective if the person in question stands with their eyes closed and then you take them by surprise when pushing them forward. This way they can’t subconsciously choose which foot to put forward.
The Pants Test
Whichever foot a person puts in a pair of pants first is the foot that should go in the front binding.
The Demo Test
A great way to decide the forward foot is to demo a water ski or wakeboard and try both your left and right foot in the front binding. Do whatever feels the most natural. Either way, you are likely to feel a little less balanced on your off-side when crossing the wake. Off-side is when your back leg is closest to the wake.
The Kick Test
Go get a ball or something like that, and sit it on the ground in front of you. Now kick it without thinking. Whichever foot you kicked it with will likely be your back foot. You want the balancing foot in the front, and the kicking foot in the back.
