Go in up to the ankles (4)
I believe the answer is:
wade
'go in up to the ankles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wade that I've seen before include "Stride through river" , "Move through sea" , "Walk through shallow water" , "Virginia who won Wimbledon" , "Paddle" .)
