Run with light steps (7)
I believe the answer is:
scamper
'run with light steps' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scamper that I've seen before include "Run quickly and lightly" , "Run about briskly" , "Proceed hurriedly" , "Skip playfully with campers" , "Scurry, scuttle" .)
