Pierre (or anyone else who wishes to give an opinion), in response to this question in an earlier thread :
Hope I don't come across as too dense , but could you please clarify exactly where these pieces of paper are supposed to be in relationship to the skis - not just anywhere between the skis I know. And presumably they should be the same size of paper in the same orientation? And where is the running surface you refer to in relationship to these two pieces of paper? Thanks.
|What is a good method to best determine binding position? Any non-subjective way to do it?|
|Book the skis bottom to bottom and slide a piece of paper in from each end. Measure the distance between the sheets along the ski and divide this by 2, Mark the ski in the middle of the running surface.
If you have little ankle range of motion mount the bindings so that this line is where the arch of you're foot just starts behind the ball of you're foot. My guess would be for each 5 degrees of ankle flexion move the binding to the rear by one cm. That would be a good starting point. Most bindings today have some fore and aft adjustments on the toe and heel pieces. Keep in mind, these are my opinions.
Measure ankle range of motion by sitting in a chair with you're feet flat on the floor. Have the femurs and the tibias at right angles to each other. 90 degrees to each other and the floor. Next lift you're toes as high as they will go with you're heels still on the floor. Measure the angle between the floor and the bottom of you're foot with a dial protractor. Less than 5 degrees is concrete ankles. less than 12 degrees is low range, Normal range is 12 to 24 and over 24 is noodle ankles. Most boots are 6 to 12 degrees forward lean.
