Ski Boot Width

So I'm in the market for some ski boots (actually bought some but not sure if they fit right). So I went to a boot fitter and tried on some Dalbello il Moro MX110s. They fit perfect but I wasn't sure if I wanted that boot yet. Black Friday came around and I got a good deal on the Il Moro IDs similar boot but diffrent liner and slimmer last. The mx110s were 103mm width and the Il Moro ID's are a 98mm width. My foot is measures 27 length and 100/101 width. I went with the 27.5 size as the 26.5 were just too tight. So my boots came in and i try them on and with the 98 width they feel to tight. I feel a some pressure points on the outside of my foot. I know boots are suppose to stretch out after a few days but will they stretch out width wise? Any thoughts on this? Maybe return these and get the ones that are 103mm. Or maybe keep them and have a boot-fitter stretch the shells. Would love to hear opinions.
