I have several pairs of ski boots size mondo 24 giving various shell fits around 14mm some a little more some a little less.
I have a Lange RS 120 SC and down sized to 23 to get a tight back end and the boot has a 1cm punch for the first two toes, and a cut and shut inner boot to go with it.
I like these boots, they were an experiment to see if they were a good match for my morphology and alignment.
I prefer a stiffer boot ( Atomic WC 150 ) but think the Lange is a better match for shell fit.
I was lucky enough to have the shell punch done in a shop which had a RS RP ZA + in a mondo 23.5 and this seemed to be a fit which would not require the toe punch or other mods except perhaps that the cuff was seriously tight and might need the buckles moved.
I know the liner is a lot thinner and this allows more space but to help me understand the siing can somebody say what the size increase is in the "+" size boot over the standard 92mm width world cup version ?
unfortunately the pair I tried were sold two days before I came to the point of going back to look at them again
