Coast-to-coast, the largest emerging skier demographic remains the all-mountain ski enthusiast. That's why it makes sense that Nordica developed their Hot Rod ski boots exclusively for all-mountain functionality. While the Hot Rod 105 isn't the stiffest boot in the Hot Rod collection (the stiffest is the Hot Rod Pro 125 by 20 flex points) we think it has all the power transmission potential that most advanced and expert skiers would require on any side of the mountain. The Hot Rod 105 features the same Full Shock Eraser (FSE) features as the Hot Rod Pro 125 without the FIS-approved heel wedge. Full Shock Eraser technology enhances the shock absorption features in your skis by providing further vibration dampening, a quality any skier who skis fast or in varied conditions will immediately appreciate. The Hot Rod 105 has a wide assortment of FSE components, including the wedge, gel liner and adjustable rear spoiler. Like other Nordica ski boots, the bi-injected shell in the Hot Rod 105 offers soft pliable plastic throughout comfort areas and rigid material where energy transfer is critical to precision edge hold. It's a great combination of performance-oriented features and essential comfort components for going all-mountain, all day.
