The 2020 Lange RS 120 ski race boot features a narrow 97mm last to offer a precise, performance race boot. The Dual Core shell utilises a blend of softer and rigid ultra-lightweight Grilamid plastic in key areas of the ski boot to enhance performance. As you drive and flex into your boots, this Dual Core material actively compresses and expands resulting in a sandwich shell construction that increases energy, rebound, and flex control. The Dual 3D Full liner features three types of high density foam that can be completely heat moulded and is pre-shaped to match the anatomic contours of your foot and lower leg alongside the shape of the boot itself. The result is incredibly precise and accurate power transmission and an unmatched out-of-the-box fit that can be further customised if required.
