People who laze around in casual footwear (7)
I believe the answer is:
loafers
This could be a double definition.
'people who laze around' is the first definition.
'loafers' can be an answer for 'people' (loafer is a kind of person). I am not certain of the rest of the definition.
'casual footwear' is the second definition.
(I've seen this before)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for loafers that I've seen before include "Comfortable shoes" , "Casual footwear" , "Casual shoes" , "couch potatoes" , "They add cargo" .)
