the boot is very much in the same vien as the Scorpion 120.
Flex and Fit:Super Stiff Flex (130) High Performance Fit // 97mm Forefoot width // Developed for high performance skiers with narrower forefoot widths in mind, Lange?s unique ?Control Fit? comes to the market with an all new mono injected shell.
Cuff Shape:The new RX shell is built with modern, efficient neutral and upright stance, derived from our Race Department World Cup boots. These feature a 4 degree ramp angle, 12 degree forward lean (16 degree with spoiler), 0 degree medial/lateral stance, and upper cuff of +1.5 degrees.
Materials:The RX is the only boot on the market that employs a Mono-injected 100mm shell. Mono-injection delivers better performance than bi-injection. Anatomical padding is polyurethane injected, and right and left foot specific, since our feet aren?t identical. Saddle stitched seams are also featured to eliminate pressure points and overlapping material thickness. Max grip soles allow maximum traction while hiking or walking to the tram.
Liners:The unique Control Fit liner consists of a true lasted liner, anatomical padding, a one piece toe box, an instep pocket, and saddle stitched seams.
Additional Features:A longer, deeper toe dam provides a tighter seal against moisture and snow. Low profile buckles are 1/3 thinner than in the past, and sits lower to the shell for stronger more precise enclosure. Also eliminates buckle ?boot out?. Last but not least, the new 97mm RX last is developed with high tech 3D imaging systems to most accurately mirror the modern foot?s anatomical shape. This includes innovative fits in the toe box, 6th toe, navicular and instep areas, while maintaining the strong Lange heel pocket.
