Shoe without laces (4-2)
I believe the answer is:
slip-on
'shoe without laces' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for slip-on that I've seen before include "Shoe, not a 10" , "Without fastening" , "Shoe without fasteners" , "Garment or shoe with little or no fastening" , "Shoe without laces" .)
