Wearing shoes dirty on the outside and badly made (6)
I believe the answer is:
shoddy
'badly made' is the definition.
(I've seen this before)
'wearing shoes dirty on the outside' is the wordplay.
'wearing shoes' becomes 'shod' (I've seen this before).
'on the outside' means to remove the middle letters.
'dirty' with its centre removed is 'dy'.
'shod'+'dy'='SHODDY'
'and' acts as a link.
(Other definitions for shoddy that I've seen before include "Gimcrack" , "Cheap and inferior" , "Second-rate" , "Poor-quality" , "Cheap, of poor quality" .)
