This age deliberately destroys footwear (5)

I believe the answer is:

sabot

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

'footwear' is the definition.
(I know that sabot is a type of shoe)

I don't understand the rest of the clue.

(Other definitions for sabot that I've seen before include "French wooden shoe" , "Carved shoe -- boats (anag)" , "This from last" , "sole support?" , "Wooden clog" .)

I've seen this clue in The Irish Independent.
