You've sold me, do you usually switch before or after the turn, or just take it as it comes? ....
I am a natural (left foot forward), and my best move is the left foot forward toeside carve, so when riding on heel side and left foot forward I do a carve and change on the way out. The change can happen any time from during the transition, just after, or not at all.
If I am riding heel side and right foot forward I switch to toe side then do a heelside carve.
The easiest time to swap feet is about 2/3s through the turn. You've just gone through the downwind part of the turn and the kite is a bit depowered and the board is almost stationary for a micro second. If you have the power running correctly down through the harness through your front foot then you can stand there for as long as you like and move your feet around.
Always move your back foot up near to the front foot. Move your weight to the back foot (about to be the new front foot). Move your old front foot back. You can move your foot back in a series of dabs rather than trying to go straight to the strap.
In general when you're a noob on a directional it's best to keep the back foot out of the strap and place anywhere from just in front of the back strap to the mid way between the front and rear straps.
