Alvida's traveling technique; first she calls on Buggy's henchmen to set up her personal ramp or "Gelände" as she calls it. She then stands at the top of it and uses her Sube Sube powers to "ski" down it with her bare feet and gain speed so she can keep on "skiing" on the ground till she gets where she wants to go. The pun here is that "Spur" can mean "ski slope" or "frictionless movement" and in this case Alvida is doing both at the same time, also "Gelände" is the German word for "ski jumping".
