Meant for a sliding fit? (4-2)
I believe the answer is:
slip-on
'fit?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for slip-on that I've seen before include "Shoe without fasteners" , "Garment or shoe with little or no fastening" , "Not a lace-up" , "Shoe without laces" , "Without fastening" .)
