evo.com | Rossignol Alpine Ski Boots > For the lighter weight aggressive skiers out there, a boot with a triple-digit flex rating is daunting and unnecessary. Drop in on the Rossignol AllTrack 80 W Ski Boots and get the wide-lasted performance you need without feeling like your trying to flex a steel beam. With enough support for the chattery upper mountain and a walk mode to help you get there, the AllTrack might just be the missing piece of the puzzle you desire to tackle the whole mountain. Shell Polyether Forefoot Last: 102 mm. Designed to accommodate wider feet. Diagonal Buckles Patented diagonally-oriented buckles provide better shell wrap and fit, and are easier to align during entry and exit. The diagonal angle pulls the foot back into the heel pocket for increased support. Thermo Optisensor 3D T3 Liner OptiSensor 3D liners deliver a new level of optimized foot wrapping, comfort and support. Strategically placed materials in three-key fit zones maximize the interaction between the foot, liner, and shell. Softer ankle and instep areas increase comfort and foot wrapping. A stiffer heel cup provides superior heel lock, increasing support and control for enhanced performance. New Thinsulate | Women's Rossignol AllTrack 80 W Ski Boots 2017
