Shoes worn by sports coaches (8)
I believe the answer is:
trainers
This might be a double definition.
'shoes worn by sports' is the first definition.
'trainers' can be an answer for 'shoes' (I have seen 'Casual shoes ' mean 'trainers' so perhaps 'shoes' could also mean 'trainers'). I am not sure about the 'worn by sports' bit.
'coaches' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for trainers that I've seen before include "Casual footwear" , "gym shoes" , "Those going on foot" , "Coach's" , "not Oxford types" .)
