Bounders who support feet (5)
I believe the answer is:
heels
'bounders' is the definition.
(I know this)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for heels that I've seen before include "Take to them and run away" , "leans to one side" , "Parts of shoes" , "Backs of the feet" , "Foot parts" .)
