I am adjusting some used skis. They have a blizzard IQ binding which is easy to adjust. The adjustment has sole length adjustments with numbers. The ski also seems to have a mounting point marked (the triangle in the picture that is by the numbers?). I am wondering if this triangle is actually a mount mark or not. If I use the correct sole length that is on the binding's adjustment, the boot midsole is way too far forward of that mark which is why I am wondering if this is in fact a mount mark. Anyone familiar with these?
