## ski 長度問題

That is short.  My son who is 80 pounds and 4 ft 10 inch uses 144cm.

When the ski is short, it is indeed easier to handle and it will be slower. But you won’t learn or improve too much since the ski will be limiting your pace to learn new skills.

What is your height and weight?  I cannot remember if you like to learn carving.  Is so you may want to rent better shape skis with more stiffness, target length between your chin and your nose.

So, to be honest, you are smearing the turn, not carving.  You are turning from your hips and rotate, instead of tipping the ankles.

It’s ok.  Too short is counterproductive.  You may not fall but you can’t learn.  Get a chin length shaped ski in the low 150s.  Learn to tip your ski and use the side cut.  If the ski is too short then you cannot learn the carving feel.  You may fall a little more at first but it will help your learning.

You are not obviously using the upper body to turn.  You are actively turning your foot which ultimately leads to the femur rotating in the hip socket.

If you want to learn carving then you need to tip your ankles, start with outside ski inside edge.  You want to ski the sidecut.  A ski that is too short for your weight and height will have a very short sidecut and turn radius, and is counterproductive to learning how to carve.  You carve by tipping the ski on the edge, bending the ski into an arc that cuts the snow.  You can overpower this if the ski is too short for your weight and height, making the ski skid.

Personally given your height and weight I would go for a shape ski in the low 150cm range.   Just start with the right ski length and learn with it.

Thank you very much! Your advise is right and reasonable. I think I should use the right length ski next time.
Tipping the ankle <- the boots is too tight and hard for me to tip the ankle, I think you mean tipping the whole legs? 教練講過我們要保持小腳和大腳成一直線，但就無講ankle 和小腳是否要需要成一直線，之前都聽過有些師兄講其實對boots 係有少少位比ankle 郁動的，所以係可傾斜少少的對嗎？

The first minute where he showed the ski on the ground, putting the pressure on the ski to make it bend, is a good explanation on the reason why you want a ski with sufficient length.

The ski boot is rigid so when you tip or roll your ankle, the boot will tilt.  That puts your skis on edge.  The point is not actually tilting the ankle inside the boot.  When you initiate a movement by tilt the ankle, you tilt the boot, which puts the skis on edge.

Don’t know what you mean by “小腳和大腳成一直線”.

Ic, I think I understand what you mean. That is right, only long ski can provide enough edge to carve. Actually I had tried y what the video teached last year, 但每次我傾斜時都有些驚驚地，主要係怕跌。有時可以做到一兩下，但速度一快又會驚，結果係唔夠膽太斜，今季希望成功。
