Sharp footwear? (8)
I believe the answer is:
stiletto
'sharp footwear?' is the definition.
(footwear with a sharp heel)
This is all the clue.
(Other definitions for stiletto that I've seen before include "Dagger with narrow blade, or a high heel" , "One may have a stab" , "Kind of heel" , "Tapering dagger" , "Thin high heel" .)
