Higher shoe part (5)
I believe the answer is:
upper
I believe this is a double definition.
'higher' is the first definition.
(higher up)
'shoe part' is the second definition.
(I know that upper is part of shoe)
(Other definitions for upper that I've seen before include "catcher of swans?" , "Stimulant drug (informal)" , "Higher in status" , "Part of a shoe; drug" , "Higher; part of shoe" .)
