I’ve never ridden a strapless board?
A Kite Alaia is really simple to use.
You place your front foot on the center-line of the board, in the middle of the board. Dive your kite & step onto the board with your rear foot; place your back foot just behind your front foot. It really is as easy as that. Initially, when you want to turn around to come back you may fall and have to water-start but there’s an explanation about that here.
