I needed a replacement for my retired rossignol X3's and the X5's fit the bill.
I wear a size 10 1/2 shoe and the 44's fit perfect. The support heal offered great control for off track skiing. A very comfortable and warm fitting boot. I especially liked the speed lacing for quick on and off. Over all great boot for on and off track skiing.
