Faded away (with one's boots on?) (4,3)

I believe the answer is:

died out

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

'one's boots on?' is the definition.
I can't judge whether this defines the answer.

'faded away' is the wordplay.
'faded' becomes 'died' (I've seen this before).
'away' becomes 'out' (synonyms).
'died'+'out'='DIED OUT'

'with' acts as a link.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
