@Jarek Thanks for the post and the link and sorry for late reply, im not very active on forums so did not see it.
After a lot of experimenting that is what worked for me, putting cleat a bit more forward on longer foot and more back on shorter one.
Or i’ll write a bit more detailed, so maybe my experience can help to others as well
After experimenting with different size shoes first and convinced my self that that will work, then experimenting with different types of insoles in same time, i realized that shape of the shoes i had in different sizes did not worked for me (Gaerne are wide heal and narrow front opossite of my feets). .
So decide to get back and to try same size shoes left/right but to be as much fit to my feet shape as possible (where i live there is not so many choices of shoes to try so have to mail order most of them without a chance to return them back if they dont fit). That why looked like good idea experimenting with different shoes from brand i can try locally…
So i realized that my old S-Works 5 worked better to my feet (narrow heal and wider in the front) and based on that i order S-Works 7 lace and in same time with chance to return them back if they dont fit i did not hesitate to do that.
I like S-Works 7 even more than S-Works 5 for few reasons:
-
They look better quality build and that will last longer
-
Even narrower clamp type heel and wider in front (great for my feet shape)
-
Better ventilation
Sizing wise right feel a bit tight but got brake in to dont be painful, and left just a tiny larger so somehow like good compromise left/right (on Gaerne if i go 43 right one is perfect, but left one too big so had to go there 42 1/2 and 43), so S-Works 7 shape worked well and even better with some insoles (green Specialized on Left, Blue on right)
Then based on this experience i also ordered regular Boa S-Works 7 and just confirmed my experience that maybe this is best i can have for my feet shape without going ultra expensive and custom.
Also on S-Works 7 shoes i have chance to move cleat even more on rear which i done on left shoe, and that helped even more.
And based on this i stocked some more S-Works 7 shoes (and good thing they were on huge discount since new model was already on market) since im not sure i’ll have a nerves to experiment again in the future
when there wont be chance to find them on stock (new version of S-Works are already different shape which i dont like and think wont fit me)
BTW, back in the past i had back problems, which i realize probably is from my leg/feet discrepancy, so considered this with cycling and beeing fixed in same position as chance to rewrite my habit
of bad left/right balance of whole body and maybe to use left feet more for walking not just cycling (and that way to fix my issue).
Even more helpful in this my experiment is that i have left/right power meter stats which i can follow if something is changing or not…
So i hope my journey ended here
and wont have to spend more time on searching for different shoes etc… 
And hope this thread will help to someone else as well…
If there is anyone else having similar problems please share it as well how u solved and what worked for u.
