Advice on ski boots- tricky situation.

Hey everyone, i need some advice on ski boots. My situation is unique as my foot is quite short, and extremely wide. (shoe size 9.5 but foot width is well over "double E" shoe width). I currently have a pair of two year old Dalbello Proton 9's in size 27.5, which after many times being "stretched" by a boot fitter are still WAY too small width wise. Does anyone have any recommendations on what to do? Also, i would prefer a boot on the stiffer side.
