Product Info

The Lange RS 70 SC Ski Boots are a real performance ski boot for advanced to expert kids or adults with short tibia lengths that come in a true 97 mm last (most kids boots are "youth wide") and have a slightly lower/shorter cuff. This is a no-frills plug boot without rubber soles and a performance flex, so be ready to rip (and sometimes slip). The RS 70 SC is also a good match for many advanced women skiers with smaller feet and shorter leg dimensions.

Product Details


Last: 97 mmA narrow last for slim and low volume feet.

Short CuffDesigned for junior skiers and women, Short Cuff (SC) design features a shorter upper cuff (15mm in back/20mm in front) providing a more natural stance to increase balance, comfort, and performance.


Flex: 70A medium flex for younger skiers or advanced, lighter weight adults.


Dual 3D Performance LinerA liner pre-formed twice in 3D. The inside of the liner is pre-formed to support the foot while the outside is pre-formed to the shape of the boot to limit movement and thus ensure superior precision and power transfer.

Power Wrap TongueSuperior leg wrapping for enhanced precision and sensitivity.

Race Fit

Shell Materials & Design



Dual Core TechnologyA new "Power Injection" method allows Lange to inject two different durometers of plastic simultaneously through 5 injection ports, with the two plastics being directed to specific parts of the boot. The harder plastic goes to the heel, spine and lower shell to retain stiffness, while the softer plastic goes to areas that wrap the foot and lower leg for comfort.
