Replying to How do you break in tongues?

Last season I ended up getting some Dalbello krypton 110. Now, these are usually a pretty soft boot but I'm only 115 pounds and 5,5. Yes, I did go to a boot fitter and we both agreed that even though they may be pretty stiff for me they would give me the best support for my wack feet because of the specific shape of the boot. After a year and over 40 days, I still haven't been able to break in the tongues as I can't flex them properly. I was wondering of they were was a way to soften the tongues permanently either by over flexing them by hand or something else in order to lessen the flex from a 110 to something that feel like a 80-90. Also if anybody knows how to get a set of softer replacement tongues that would fit that would be greatly appreciated. Anything helps really, thanks so much
