The Rossignol Allspeed 100 is an awesome intermediate boot that doesn't skimp on performance, but won't make your foot feel like it's been chewed on by an alien at the end of the day. The Thinsulate insulated liner is heat moldable and the shell is optimized to provide the power you need without the weight that you don't. If you are looking for a comfortable pair of boots to take your skiing to the next level then put these on your radar.
102mm last: Slightly wider than average to give a great fit for most skiers. This last was designed to fit pretty much everyone, but really wide feet, or the opposite, should look for different lasts more appropriate for their foot types.
Tongue Pull: A loop of fabric at the top of the tongue helps in putting on and removing the boots. Pull it forward and to the side and your foot should slide right in.
This liner allows pin pointed customization for supreme comfort and warmth with dual density 3D padding and super warm Thinsulate Insulation.
Rossignol Sensor Blade: This is a new anatomical ski boot design that has reinforced rear support. Sensor blade reduces weight and increases torsional rigidity which helps drive power and energy directly to the ski.
Micro-adjustable aluminum buckles: These aluminum buckles can be moved to adjust for size, so if the default position of the buckle and the teeth is too wide or too narrow, you can move it until it fits.
100 Flex Rating: This boot is pretty stiff, but not insanely stiff. A boot of this level is pretty good for upper-intermediate to expert level weekend warrior that is looking for something stiff enough to provide high-end response, while being wearable for an entire day of skiing.
