Riddle of shoes son moved to the furthest possible place (8)
I believe the answer is:
strainer
'riddle' is the definition.
(riddle can mean a sieve or strainer)
'shoes son moved to the furthest possible place' is the wordplay.
I cannot really see how this works, but
'son' could be 's' (genealogical abbreviation for son) and 's' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
The remaining letters 'rainer' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for strainer that I've seen before include "to keep out foreign bodies" , "one won't let everything go through" , "Tea leaf remover" , "someone trying hard" , "Person making too much effort" .)
