Football shoes (6)
I believe the answer is:
cleats
'football shoes' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cleats that I've seen before include "Projections around which ropes are secured" , "Devices on board ship for fastening ropes" , "On which to fasten ropes on board" , "Footwear stabilisers found in castle" , "Projections around which a rope can be tied" .)
