Salomon X3 lab medium flex

Hey guys, just wondering if anyone had any info regarding the forward lean of this boot. It's the white 2011/2012 model in the 140 flex--thanks smile.gif

what is really important, is, what will the forward lean be of your tibia(lower leg) in this boot---this is determined by the girth of your calf muscle in the boot and the forward lean of the boot---these boots, in that year, had about 15 degrees if forward lean.

 

the current X-pros have about 10 degrees (which can be changed when the shell is heat molded)---i say "about" because, sometimes you can measure a set of boots and they won't have the same amount of forward lean.

 

so---those older boots will push your knees forward more, especially if you happen to have large calves, this can really mess up your fore/aft balance position and cause you to ski in the back seat.

Just to be clear, these are the world cups, not a consumer race version. I don't have very large calves at all...14" in cirumfurence. My bsl is 293, I wear a 7.5 us men's sized shoe. Not sure how to measure how long my tibias are. Earlier this season I put some 2mm shims under the toe pieces of my bindings (4mms per toe piece) which brought my knees over my toes when plumbed.

I do seem to have better than average rom in the ankle. When I line my toes up the the edge of a wall and flex forward, I can move my knees WELL past the wall (say 5-6 inches) while keeping my heels down.

is that 14 inch calf circumference measured at the top of the liner or at some other point-----?

 

If the answer is the top of the liner, then this is why you needed to add toe lift---this affects two issues determining fore/aft position.

it lowers the heels relative to the toes and makes the boot more upright by a small amount.

 

I think this is a poor way to affect the fore/aft needs of most people.

 

Since,as a boot sole is shortened by a centimeter for each size change the boot sole center moves toward the heel of the boot by 5mm(for each boot size change)but the forward lean angle doesn't change  when the manufacturers design their boots.

 

You re in a size 25 mondo shell and have large calves (for that size boot) which pushes your knees forward too much

 

If you were to place the boot heel against a vertical surface and measure to the liner at the top of the boot shell---you only need 44mm of forward lean when measured this way, to be centered up correctly, then you would not need toe lift.

Perhaps I should remove the the spoilers that are velcroed on the back of the liner and re-plumb...thanks for your time! smile.gif
