Does anyone know the lean angle of the 2013 Salomon X3 120 CS boot? And of the 2012 Salomon Instinct 90 CS women's boot?
Can't find those numbers anywhere. Thanks
There is no way to compare apples to apples. You can get an approximation but nothing more. Measuring from a wall to the boot ignores boot height and unfortunately varying boot heights make your measurements inaccurate.
If you are trying to compare boots by comparing manufacturers numbers you are wasting your time. If you are trying to compare based on your own system it is still not great. Best thing if boots are in your hand is to put them and determine which you like but varying
boot ramp angle will still blur your findings.
If the reason to know is so you can figure out which boot to purchase from an internet site then you are making a mistake anyway for oh so many reasons.
Tecnica does not publish a forward lean angle(unless things have changed) they measure to the back of the liner from a vertical line at the heel of the boot. I just measured a 24.5, 25.5, 26.5 and a 27.5 Lange boots and they all measured 60mm from a vertical line to the liner---by the way not all the same models either. I have done this with other brands with the same results. I am not saying all boots have 60mm when measured here---but you can get a feel for the amount of forward lean.
I checked with Salomon and the published forward lean angle on the X3 is 16 to 18 degrees (a ton for forward lean) read tired quads here, these would measure out at about 82mm from a vertical surface at the boot heel to the back of the liner.
Just to ease all your bootfitters' minds: I would never buy a boot online. Since virtual bootfitting doesn't exist yet, it would be quite pointless, IMO.
I own the 2013 X3 120 CS and I was just wandering if these things (forward lean angle) are facts you guys would know. They ski great and I love my boots to bits (tried just about anything a year or two back), just couldn't find any numbers.
There was an artical that suggested that boots with quite a bit of forward lean (16 degreees or more) would negate the turning ease of rockerd or early rise all mountain skis. Do you have any opinion or theory on that?
I'm not certain the forward lean angle negates your ability to pressure the ski tips more on one design ski than another. However, as forward lean increases I would say it is more difficult to move pressure to the front of the ski.
Forward lean is but one of four parameters to consider and coordinate on the sagittal plane. A person's lower leg length, dorsiflexion range, lower leg circumference, and a few other factors affect forward lean ideals.
Most boot fitters will choose and/or adjust the net forward lean of a boot according to the needs of the skier's morphology and range of ankle dorsiflexion by adjusting the ramp angle (internal boot board angle) and cuff forward lean to achieve an appropriate neutral ankle angle (closed/open). Then they will look at the skier clicked into their bindings to assess the delta angle (created by the difference in height between toe height and heel height) and change this angle to achieve the desired lower leg angle. Lastly, the fourth parameter is the binding mount position which affects where the skier stands over the ski's balance point or sweet spot.
So it is a bit over simplistic and short sighted to consider forward lean alone without assessing ALL the pieces of the fore/aft puzzle and putting them together in a systematic scientific manner to achieve optimal results......Or you can just throw darts and hope for the best?
This wasn't my own theory. I read it here: http://www.outsideonline.com/outdoor-gear/mens/Blizzard-Bonafide.html (last paragraph). An interesting thought.
