Snow runners kiss back to front (4)
I believe the answer is:
skis
'snow runners' is the definition.
(I've seen this in another clue)
'kiss back to front' is the wordplay.
'kiss' anagrams to 'SKIS'.
Though, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for skis that I've seen before include "Travels on snow" , "Swoops downhill" , "Engages in a winter sport" , "On these in slalom" , "Snow runners" .)
