There is a point in carving turns where it feels more difficult or scary to achieve greater edge angles. For simplifying this post am roughly saying beyond where your your boots are tilted about 45 degrees to the slope. Perhaps you've noticed in video of you "ripping" down the groomers and feeling like you're just inches from the ground you see it's actually much further away. You're barely tipped over at all. Why is this? Is it a matter of fear? Is it a lack of strength? What other factors could be at play? I'd like to share one insight around this particular frustration point in getting your skis tipped over further.
Firstly why is it something you want to even bother pursuing? What is the reward for taking the risk? What do you gain by moving yourself further inside each turn past 45 degrees? Beyond this point you're really either going to make it or break it and fall could really hurt. And if you're not a ski racer and don't need to win a race what's the big deal? The reward I believe is this; greater control of your turn shape whilst still riding a stable carving ski. Remember turn shape is what gives you speed control so having control whilst carving on steeper slopes is the goal for most skiers.
You need to understand that there are only two ways to make a ski turn tighter. One you twist it or two you tip it on its side further over so it can bend more. Twisting the ski is fine and necessary in certain situations but it creates friction and is less stable as the tail of the ski is not following a similar path to the tip of the ski. Not great for higher speeds. Tipping the skis over to higher edge angles allows us to keep the skis stable so how come it produces a tighter turn? It's because of the parabolic shape of the skis. The hourglass shape allows you to bend the middle of the ski but only when it is really titled over. Look at the photo below to see how little the ski bends at roughly 45 degrees to the slope.
