Sprays water, ruins shoes (5)
I believe the answer is:
hoses
'sprays water' is the definition.
'hoses' can be an answer for 'sprays' (I've seen this in another clue). I am not sure about the 'water' bit.
'ruins shoes' is the wordplay.
'ruins' indicates an anagram.
'shoes' is an anagram of 'HOSES'.
Can you help me to learn more?
(Other definitions for hoses that I've seen before include "Flexible pipes for conveying liquids" , "Lengths of piping" .)
