Those who steal shoes (8)
I believe the answer is:
sneakers
'shoes' is the definition.
(sneaker is a kind of shoe)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for sneakers that I've seen before include "US canvas shoes" , "soft-soled canvas shoes" , "Gym shoes" , "Canvas shoes with rubber soles" , "Casual shoes" .)
