My younger brother is in the MDF camp of skis boots. He still skis the SX whatevers. I found an old pair of my wife's SX's in the basement and they were the men's model and in good shape. He was absolutely thrilled when I gave them to him (was going to throw them out then I remembered he skis them).
I actually tried them for one day of skiing, "back in the day". I have a long, narrow, "Lange" foot but I wanted to see what everyone was talking about. To me, the thing was you could adjust the boots with a combo of rear cable, instep cable, and fore foot cable to almost any foot shape. The liner was pretty padded and comfortable too. If you couldn't get them adjust to your foot, you went up or down a size until you could. I didn't like the heel pocket, but I suppose you would get used to it. For me, the size boot narrow enough to fit my foot was not long enough. I didn't know about toe punches back then. Not even sure if they could be modified. I skied the correct width boot for one day and they performed well, but my toes were bruised and the boots were just too short for me. I stuck with my Langes.
They were easy to get on and off, which is why they were so popular I think. Personally, I was so used to working the buckles on the front, it felt weird to be working things on the back of the boot. Once it was adjusted properly, you just clamped the rear buckle and your done. If I remember right, the instep adjustment was on the rear buckle as well, as a turnable thumb screw. Probably more detail than called for, time to end this.
