Dancing feet left without skin and exhausted (6)
I believe the answer is:
effete
'exhausted' is the definition.
(I've seen this before)
'dancing feet left without skin' is the wordplay.
'dancing' indicates anagramming the letters.
'without skin' means to look at the middle letters.
The centre of 'left' is 'ef'.
'feet'+'ef'='feetef'
'feetef' is an anagram of 'EFFETE'.
'and' acts as a link.
(Other definitions for effete that I've seen before include "Weak, effeminate" , "Over-refined and ineffectual" , "Feeble, having lost vitatlity" , "Affected, ineffectual" , "Over-refined; weak" .)
