Cool deeppow! Glad you are here!
Sigh. For the record, I am NOT bashing. Not at all. The Amfit system is DAMN close. Used properly it is CAN be a very accurate system, and will produce a good product. Using a computer system properly is a great way to get repeatable, objective results. I spent years in CAD/CAM and I love the measurement capability, and repeatability..
I also happily skied for years in my Amfit footbeds. But I like my new ones better! The new ones work better for skating as well... However, it IS more labor intensive.
BTW, your references to other sports are inappropriate for skiing, as the footbones move differently in walking/running.
The main limitation of the AMfit blank... I will review this limitation, as it's mostly in the material(s) used, not the "system":
The arch of the foot needs to flex and flatten a little as the foot articulates (to the Big Toe). If the arch is made with dense, unyielding material, it will hinder the foots articulation. Too soft of an arch, AND one that lacks "springback" (return to original shape, elasticity) will not support the foot, or assist in going to the Little Toe.
Amfit "tweak": Manually grind the material under the arch, appropriate to the weight/strength of the skier. Best done in stages, but just don't go too far, or it will be too soft, and won't support the foot... This is closer to the "ideal".
Existing materials used in Amfit systems do NOT spring back, when undercut... Darn!
So what else can you use? Doubtful that there is a "machineable" blank avilable now that will do this, altho perhaps some dissimilar materials, in layers, might give the "springy thingy" underneath. This would probably require different blanks, and "depth of layers" to accomodate (the above mentioned)thicker/thinner feet and or available volume under foot/in the boot.
I understand spinhelis dilemma, and it does sound like it was made improperly. So he should/could get a new one made, eh?
Maybe a simple grind and glueing under the arch, with a suitable material to "spring back, as another tweak. Hmmm, got me thinking again. Dangerous, ain't I?
One more thing. Where does alignment end? When it WORKS. However, I agree some clients like to fuss too darn much, and don't understand that it's a blend of technique AND proper alignment to improve; i.e. it's not the tune, you suck
. YIKES! How do you say that gently?
Personally, I suffer from very bad skeletal alignment. Very assymetrical. Held me back for years. It's very important, especially with shape skis. I am not alone, or that unusual.
I won't even get into all the problems with ramp angle (bad boot design) and inappropriate "heel lifts" right now...
Please check your premises deeppow, this is not competition, rather it's about making a more functional product for MY clients. Would love to discuss this more...
You can click on the link that is my "handle", if you prefer to discuss this privately. Heck, I would RATHER work (and send my clients to) a shop that has selection, and cares about the results. Which MOST Shurfoot employees do, IMHO.
Please remember that this IS a forum, defined as a healthy exchange of ideas, mmmm, k? I suggest you listen to your (possibly ex) customers in this forum, eh?
One more thing, the "idgits" I referenced, absolutely NOT Shurfoot. Not Precision, or Racers Edge or... never mind.
Respectfully (quite!) yours...
