evo.com | Rossignol Alpine Ski Boots > Finally, a comfort boot that doesn't fit like a breadbox. The Rossignol Allspeed 100 Ski Boots keep the heel relatively snug but widen the forefoot to a reasonable 102mm. A medium 100 flex provides a balance between power and comfort, and lets you flex your ankles naturally in softer conditions and technical slopes. Last: 102 mm Comfort fit designed to accommodate wider feet. 4 Micro-Adjust Aluminum Buckles Sensor Blade Eliminates excessive shell materials to reduce weight, while reinforcing torsional rigidity. The asymmetric molded shell structure directs power to the front of the boot for optimized power and energy transmission. Custom Optisensor T3 Liner Customisable liners made from mono-material polyethylene. Dual-density 3D molded padding in key fit zones and customizable liner provide a new level of optimized comfort, warmth, and support. More rigid material in the heel area guarantees increased support and precision. Anatomical ankle areas feature softer customizable padding which visually molds to each individual skier for absolute comfort in this sensitive area.
