Boasts about wooden shoes (6)
I believe the answer is:
sabots
'boasts about wooden shoes' is the definition.
(I've seen this before)
'boasts about' is the wordplay.
'about' indicates anagramming the letters.
'boasts' is an anagram of 'SABOTS'.
(Other definitions for sabots that I've seen before include "Wooden shoes for the French" , "Boasts about wooden shoes" , "Shoes with wooden soles" , "French clogs" .)
