I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for skis that I've seen before include "More than one runner" , "Travels on snow" , "Engages in a winter sport" , "On these in slalom" , "Snow runners" .)

I've seen this clue in The Hindu.
