The Rossignol Alias Sensor 120 is a great ski boot for those of us with a little bit wider foot. This is the boot that I used almost entirely last season. It’s really hard to find a stiff flexing boot with a wide last, but that’s exactly what you get with the Rossignol Alias Sensor 120. It’s truly a wide width performance boot. Often times wider boots have a little bit wider heel pocket as well, and heel hold suffers a bit. But the Rossignol Alias Sensor 120 uses Sensor Fit technology which uses the same heel pocket, but widens the toe-box. This gives you great heel retention and response in the boot, but will fit a wide foot. Because of this they are able to up the flex on this boot as well. At 120 it’s not a race boot, but should be stiff enough for most riders, even those who are a bit heavier and those who are aggressive. The Sensor Fit Liner is also very comfortable, and is stitched to reduce any pressure points. In addition the self-molding tongue helps make the fit a bit more comfortable. It did require a little modification to make it fit perfectly, but it is really rare that you find a boot that fits perfectly right out of the box. I will say that the liner tends to pack out pretty quickly, but for me it still fit pretty well. I did find I need to crank the buckles down a bit more now than I did at first. I also found the flex a bit soft when I skied very aggressively. Bigger skiers will probably find it soft in less aggressive situations. I still love this boot, and i do find that it’s a great combination of performance and comfort. Overall The Rossignol Alias Sensor 120 is a great boot for lighter aggressive skiers, or heavier intermediates with larger feet. It’s comfortable, relatively stiff, and I find it great for just about any terrain.
