Shoe seller paid badly (10)
I believe the answer is:
espadrille
'shoe' is the definition.
(I know that espadrille is a type of shoe)
'seller paid badly' is the wordplay.
'badly' is an anagram indicator (letters in the wrong order).
'seller'+'paid'='sellerpaid'
'sellerpaid' with letters rearranged gives 'ESPADRILLE'.
(Other definitions for espadrille that I've seen before include "Cord-soled shoe" , "Plaited fibres in its sole" , "you put your foot in it" , "goes on foot" , "Pale idlers (anag.)" .)
