In light footwear, turn and throw oneself down (4-4)
I believe the answer is:
flip-flop
But I can't explain it at all!
(Other definitions for flip-flop that I've seen before include "Shoe held on by a toe-thong" , "Rubber-soled sandal" , "Sandal held on by a toe-thong" , "Light shoe" , "Rubber sandal" .)
