Walk very quietly (3)
'walk very quietly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tiptoe that I've seen before include "''... through the tulips'' (Tiny Tim song)" , "Walk delicately - musically through the tulips" , "Walk very quietly with heels raised" , "Lightly pad" , "Be careful" .)
(Other definitions for pad that I've seen before include "Tread softly" , "Helicopter landing area" , "Protective guard; home" , "wearing this?" , "protection for member" .)
