Field-guide displays footwear (7)

I believe the answer is:

ghillie

I'm a little stuck... Click here to teach me more about this clue!

'footwear' is the definition.
(ghillie is a kind of footwear)

I don't understand the remainder of the clue.

(Other definitions for ghillie that I've seen before include "Scottish angler's helper" , "fishing guide" , "Highland attendant" , "Scots hunting attendant" , "sportsman's attendant" .)

I've seen this clue in The Telegraph.
