Lange's Secret Sauce: Dual Core Technology
Lange ski boots have long been known for their exceptional performance, often attributed to a 'secret sauce' in their manufacturing process. This secret lies in their innovative Dual Core technology, introduced last season. This technology involves injecting two different densities of plastic simultaneously into the boot's mold, creating a unique sandwich construction.

The harder durometer plastic focuses on power transmission in the chassis and back of the boot, providing exceptional responsiveness and edge control. The softer durometer plastic enhances the wrap and comfort around the foot, ensuring a snug and precise fit. This combination creates an energetic tension within the boot, similar to a golf ball's layered construction.

This isn't just about comfort; the Dual Core technology significantly impacts performance. It allows for a more aggressive, responsive feel when skiing, enhancing the skier's ability to carve powerful, precise turns. The energy generated during a turn is then released smoothly, leading to an incredibly efficient and powerful skiing experience.

Fit and Comfort: Out-of-the-Box Performance
Lange's commitment to fit is a key aspect of their design philosophy. While there might have been misconceptions about Lange's fit in the past, they've significantly improved their fit solutions. They collaborate with a global network of bootfitters to address the needs of modern skiers with diverse foot shapes.

The Lange RX 120 offers a strong heel cup, crucial for stability and preventing heel lift. This, combined with a more spacious forefoot design, provides a comfortable and secure fit for a wide range of foot shapes. The overall design prioritizes a natural stance, promoting an upright and balanced skiing position, enhancing performance and reducing fatigue.

Many skiers, including Jonny Moseley, have reported remarkable out-of-the-box comfort and performance with the RX 120. The boot's design allows for immediate precision and power transmission, leading to an enhanced skiing experience.
Forward Lean and Ramp Angle: Modern Ski Design
The Lange RX 120 boasts a 12-degree forward lean without the spoiler, promoting a more natural and upright skiing posture. This is perfectly aligned with modern ski designs and their rocker profiles, allowing for easy turn initiation and a more balanced feel.

This upright stance is advantageous for a variety of reasons. It promotes better pressure distribution across the skis, improves control, and allows skiers to maintain a comfortable, less fatigued position throughout the day. The reduced need for aggressive forward lean is a welcome improvement for many skiers, enhancing the overall skiing experience.

The design's focus on natural stance ensures compatibility with various skiing styles and snow conditions. Whether you’re carving precise turns or navigating challenging terrain, the Lange RX 120 facilitates efficient power transmission and exceptional control.
