Do not get boots which are too stiff. This is the most common fault that young racers make when they purchase new boots. The boot may flex a little in the store, but outside when the temperature is well below zero, if the boot is too stiff.

If you are knock-kneed or bow-legged your ski will not sit flat on the ground. A bow legged person will tend to catch an outside edge on a turn.

Women's boots are designed to allow for a slight knock-knee position, and men's allow for slight-bow-legged.

This can be corrected buy either
1. Putting a wedge shaped plate (cant) under the binding. Or
2. A cuff adjustment on boots with this feature.

Remove the footbed from the liner, and drop it into the empty boot shell. Have the athlete step into the shells and lightly close the upper buckles to approximately the same settings used when liners are in. No need to do up the power or Booster strap. Adjust the width of the athlete’s stance using the same method as when performing a traditional alignment analysis or drill. With ankles slightly bent and the leg shaft floating inside cuff, visually inspect for consistent spacing around the leg as it corresponds to the cuff. Hopefully, there are equal gaps in all areas. But, you may find that one side of the leg is much closer to one cuff wall than the other, indicating our earlier terms “bow-legged” or “knock-kneed”.
