I've been playing around with the height and angle of the heel lifts. I do have limited dorsiflexion and one foot is better than the other( more dorsiflexion). I have dobermann pro 130's. I'm 6 1' 200 lbs 34 in inseam
I have found the following
higher heel lift - more heel contact on steep groomers, better carve, but in the backseat when skiing bumps
lower heel lift - no backseat seems like better fore/aft balance in bumps but , less forward power.less power in the heel, less heel contact in heel cup on Groomers( note that I said less not none)
Now the questions.
1) if I have more dorsiflexion in one foot than in the other, is it advantegeous to have one heel lift higher than the other to even out the dorsiflexion on both boots?
2) are there any tests, like parallel quads or something, that I can do in my orthotics or ski boots that will allow me to dial in the proper heel lift height for proper heel contact? heel lift too high and heel contact starts moving toward front incline of the heel pocket in the orthotic. ( the boot is not too big - this just what I feel in the heel of the orthotic without the boot even on. only happens when I flex. Without heel lift standing erect both feet feel comfortable in orthotic.
3) Should I have equal height heel lifts under foot?
We are talking of heel lift here of 1/4 to 1/2 inch on top of the bootboard. Should this be more?
I form the heel lift ramp angle by cutting a cant in the shape of a heel, and overlaying it with 1/8 inch thick rubberized cork. The cant has the fat side toward the back of the heel. layering serveral cants increases heel height and ramp angle
