Notes the feet are wobbly and weak (6)
I believe the answer is:
effete
'weak' is the definition.
(thesaurus)
'notes the feet are wobbly' is the wordplay.
'notes' becomes 'ef' ().
'are wobbly' is an anagram indicator.
'feet' with letters rearranged gives 'fete'.
'ef'+'fete'='EFFETE'
'and' acts as a link.
(Other definitions for effete that I've seen before include "Affected, over-refined" , "Worn-out, decadent" , "Spent; degenerate" , "Feeble, having lost vitality" , "Decadent - worn out" .)
