The Rossignol Alltrack Pro 110 women’s ski boot is the stiffest and best performing all mountain boot in Rossignol’s line. At first look all we noticed was the soft faux fur sticking out the top. Sure this looks comfortable, but comfortable boots don’t always mean high performing. But this boot is seriously soft on the inside, and feels quite comfortable for a ski boot. It does have a moderately wide 100mm last, so it’s designed for those of us with a medium wide foot. If you have a lot of extra room in the foot, it’s just not going to perform that well. Out of the box comfort is pretty good, and all that faux liner feels really nice. The toebox offers a good amount of room for a wider foot, and it feels really warm. The Shell is made with Rossignol’s Sensor Grid tech which helps the shell wrap around your foot better. I’m not entirely sure how it works, but the shell does feel pretty conformed to the foot. This is going to seriously help performance, and allow a good amount of power transmission from the foot to the ski. The Rossignol Alltrack Pro 110 does have a 110 flex, which for most women would be pretty high. However, we feel that the flex isn’t quite as stiff as it might suggest, and most advanced to expert skiers won’t have any issues with flex. The Rossignol Alltrack Pro 110 does have a relatively neutral stance, so it’s not real fatiguing either. You just need to stay forward so you don’t get thrown backseat. This will be much easier for advanced skiers than intermediates. The Rossignol Alltrack Pro 110 also has a hike mode that can be used when hiking in bounds or out of bounds terrain. The sole of the boot also has an interchangeable sole with WTR (walk to ride) capabilities. The Rossignol Alltrack Pro 110 is a great boot for advanced women skiers with a medium wide foot. It’s comfortable, and performs well all over the mountain. The 110 is almost perfect for aggressive skiers, but not too much that most women will find it too stiff.
