Sorry for my ignorance, but what is the difference between switch and toeside?
Switch as mentioned in the post above refers to riding with your less comfortable foot forward. I am a natural footer (left foot forwards) so when I switch I put my right foot forward.
Toeside is when you dig the toeside edge of your board into the water, as opposed to heel side (standard kiteboarding stance) allowing you to travel in the other direction but keeping your comfortable foot forward.
