Fable of the foot? (6)
I believe the answer is:
legend
'fable' is the definition.
('legend' can be a synonym of 'fable')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for legend that I've seen before include "Traditional story - inscription" , "Caption; very well known" , "Story from long ago" , "King Arthur" , "One always remembered" .)
