Product Info

The Lange RS 90 SC Ski Boots are a real performance ski boot for 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 stiff flex, so be ready to rip (and sometimes slip). The RS 90 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.

Flex: 90 A medium flex for beginning to intermediate level skiers.

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.
