I have maybe 1 finger or less shell fit, depending on how you measure.
fit is ok, but my toes get crushed lenghtwise.
(i already tried different liners, footbeds, etc.).
So, the problem really is the length in the shell.
I guess my options are to grind either the heel pocket or the toe box.
what is more effectice - i guess the toe box, as i don´t really push into the heel pocket 100%.
i wil also consult a bootfitter, but whant to think about it beforehand.
oh, and how much can i get, i thought 3-5mm would be ideal.
