Shoe kept in shoebox for dryness (6)
I believe the answer is:
oxford
'shoe' is the definition.
(oxford is a kind of shoe)
'in shoebox for dryness' is the wordplay.
'in' says the answer is hidden in the clue.
'OXFORD' can be found hidden inside 'shoebox for dryness'.
'kept' acts as a link.
(Other definitions for oxford that I've seen before include "River in Newcastle" , "city producing different make" , "University - shoe" , "No odd fixture (anag)" , "Famous 16" .)
