Socks son pulled up, the loafer! (4)
I believe the answer is:
shoe
'the loafer' is the definition.
(I've seen this in another clue)
'socks son pulled up' is the wordplay.
I cannot quite understand how this works, but
'son' could be 's' (genealogical abbreviation for son) and 's' is present in the answer.
The remaining letters 'hoe' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for shoe that I've seen before include "Winkle-picker, for example" , "Foot cover" , "Where a dealer stashes a pack" , "Trainer maybe" , "eg Trainer" .)
