Alrighty I'm not trying to reply on my phone so this should be much easier!
I probably should separate my personal experience with pods from others. After all, each pod is an individual and deserving of being treated as such rather than lumped into a group.
I agree that bootfitting can be improved with a good biomechanical understanding of foot function.
How important do you think windlass function is in a nearly stationary foot in a skiboot? I do agree than an evaluation of the STJ axis is important - it can determine a great deal about foot geometry and function.
I see, I wasn't aware that a valgus wedge would help to facilitate windlass. Interesting. I need to break out my anatomy books and focus more attention on that. I do know that supinatus is a symptom and correcting the root issue is the first step in restoring (or initiating) proper foot function.
So supinating the MTJ effects an eversion of the ff? That makes perfect sense. How about limiting factors in the STJ such as ROM and joint flexibility? Treatment should also focus on those aspects, yes? Some stretching could be quite useful I would imagine.
I'm just not sure, with my admittedly and obviously limited knowledge, of how windlass function is that important in a skiboot? Could you explain this further please?
haha well yes, my stabs are not fair, and as I already mentioned I should probably leave my personal experiences out of it. No doubt about that. The irony is that my actual academic training is very much centered on objectivity, which I am not always able to apply as well as I'd like. It doesn't help I've been very stressed over the last few weeks, but that is no excuse.
I think extensive research of how the foot functions when nearly immobile within a rigid skiboot could be of great value. I know research and studies have been done before, but from what I have been able to find most of it is dated and could use updating based on modern podiatric theories.
Yes i'm not sure if I expressed what I met about the calc being jammed, but you seem to understand what I'm trying to say. I really think it is fascinating how the foot functions.
I'm pleased that I was able to evaluate the effects of the ROM limitations when accomodating a varus heel or ff foot position, and yes any significant heel lift could start getting bulky in a boot.
I see your point on where to use what. For the record I agree with you, but I think a combination of the two might prove the most useful to skiiers. I understand the difficulty that applying a wedge of any type (or really any orthoses) within the boot could cause significant problems. The slightest change in the orthotic can lead to significant changes in the mechanics of the foot. However, in defense of myself, it has been noted in many cases where patients have used the wrong orthotic in the wrong foot and have ended up being better off for it. Orthotics and their use is still most definitely an art. I believe this is due to the fact that each foot is unique, and there is no way to come up with a general truth that applies to all feet as regards specific function and specific, individual feet.
Thank you for the detailed response!

btw superhero i reread one of your posts and i believe that you need to seperate ur own personal experiences with pods with those who are in the know...most dont have a clue about bootfitting and dont pretend to...but i believe bootfitting can be improved with an enhanced biomechanical understanding of how the foot functions.
For ,if you think that a client is sittng in their skii boot in too much of a pronated position you can take a step back and assess like a podiatrist would and you could establish the position of the STJ axis - this inturn will indicate where you want to apply the supinatory foot. You could do a jacks test and assess windlass function. STJ and MTJ range of motion, Ankle dorsiflexion...etc etc...
A ff valgus post does more than 'correct supinatus' (no one really bothers to do this it just happens when you reduce the supination moment acting on the distal-medial collum) a valgus wedge facilitates windlass...there are alternatives to valgus posting like reverse mortons, kinetic wedges, met pads etc. you are missing the point with supinatus that is a symptom no a cause, supinatus only shows how much force is acting on the medial column...which is caused by proimal issues i.e. a medially deviated STJ axis or the difficulty/inability to facilitate windlass.
remember if you want the stj to supinate you want the mid tarsal joint to evert/pronate and vice versa.
I think windlass is still very important to skiing. for both the average joe seeking comfort and high performance skiiers.
That said, I can see how you might want to invert/evert the foot relative to genu varum/valgum it is something I believe needs to be explored. in which case why wouldnt you just cant the sole of the ski boot and deal with any foot issues seperately?.
I think cycling is very different to skiing also, one thing is in common is the goal of linging up the ankle and knee joints to make cycling more efficient...but in cycling you have no orther choice but to correct in the forefoot because that is the only place which is experience a ground reation force...and what you are attempting to do has nothing to do with the foot.
I don't believe it is important to 'balance rearfoot to forefoot relationships' nor does anyone who has a sound understanding of the modern theories of podiatric biomechanics.... and yes you need to think like an engineer.
Have you looked up any of the recommendations i suggested? What did you think?.
I also recommend you stop taking general stabs at the podiatry profession with the development of research technology it is evolving at a rapid rate ---those whom you have had bad experiences with are living in the past are not the ones on podiatry arena...the research conducted is being used by more than podiatrists (its not like some secret that only pods know).
For the record I would love to conduct some research how the foot functions inside a skiboot and the ideal position for the foot to be in its why i am posting here.
I think superhero i think you are trying to run before you can walk...go back study ur anatomy, learn about windlass, learn about biomechanical asssessments and what they mean.
how do you suppose the talus jams with the calc the two joined to from the stj? ...but i think i know what ur saying...yes a heel lift would be the solution...but ur getting mighty bulky in ur boots...if u wanna align the foot/ski with the lowerlimb then just cant the boot. if you want to improve fit and function of the foot inside the boot then use orthotics how would you achieve what you want to inside the boot use podiatric biomechanics!
