Like wearing boots? That's great (4-3)

Ross

I believe the answer is:

kick-ass

'great' is the definition.
(kick-ass can informally mean impressive or great)

'like wearing boots?' is the wordplay.
'like' becomes 'as'.
'wearing' indicates putting letters inside.
'boots?' becomes 'kicks' (booting is a kind of kicking).
'as' placed within 'kicks' is 'KICK-ASS'.

'that's' is the link.

I've seen this clue in The Independent.
