Boss at ground providing footwear (6)
I believe the answer is:
sabots
'boss at ground providing footwear' is the definition.
I can't tell whether this defines the answer.
'boss at ground' is the wordplay.
'ground' is an anagram indicator ('grind' the letters into a new form).
'boss'+'at'='bossat'
'bossat' anagrammed gives 'SABOTS'.
Can you help me to learn more?
(Other definitions for sabots that I've seen before include "Wooden shoes for the French" , "French clogs" , "Shoes with wooden soles" , "Boasts about wooden shoes" .)
