Posh trend — pace about bare floorboards? (10)
I believe the answer is:
uncarpeted
'about bare floorboards?' is the definition.
(uncarpeted could describe bare floorboards)
I don't understand how the rest of the clue works.
(Other definitions for uncarpeted that I've seen before include "Missing rockets, perhaps" , "like hard landing?" , "out of Axminster?" , "(Of floor) not softly covered" .)
