Lange Super Banshee Ski Boots 2010: The Lange Super Banshee Ski Boots are built using the powerful RL 11 shell. This shell has the long flex pattern that Lange is famous for which allows the skier to control how much power is going into the ski. Used for years on the World Cup but Downhill and Super G skiers, the RL 11 shell get a few tweaks for all mountain skiing. Items like an elastic power strap, shock absorbing toe box and boot board, external gel tongue pad and optional shin laces absorb vibrations and keep the boot comfy. Vibram soles help to keep the sole side down when hiking and dancing.
