How important is ski boot flex?

Higher flex numbers are primarily found in high-performance or race boots. You can best feel the flex of your ski boot when bending forward. The higher the flex, the higher its resistance. This makes your boot stiffer and somewhat less comfortable to wear, but also gives you better energy transfer from leg to ski.

What causes ski wobble?

A good stance must:

Be able to absorb bumps through the legs and allow the body to flex. This means that the knees must be bent, as well as all other joints. There should be no joints that are straight as they must all be able to move in both directions. Have the skis in the correct position.
