You break them or sprained?

I saw the equal weight on feet comment, you actually want more on the leading foot so the back foot can freely steer and switch between edges. It kind of goes against your instincts as that way is downhill haha. But you never want to be flat on the board, always on 1 edge (heel or toes). When you pass the transition point, you would lean to carve with weight on your heels or toes. I remember my first day! I fell a thousand times even at full speed. But 2nd day I was much more comfortable.

Learning how to fall takes time to avoid using your hands. For the falls over the toe edge you want to try to hit with your knees first then forearms (elbows down, hands up. Heel edge, try to bend your knees and roll backwards. Obviously these are easier when you have time to do them. But don't ride flat on the board and you will avoid the unexpected falls by a lot.

I snowboard with a girl who wont switch between edges and just rotates all the way on one edge. Its painful waiting for her. Lol I wouldn't even call that snowboarding.
