Leaned over as one mended a shoe (6)
I believe the answer is:
heeled
'mended a shoe' is the definition.
'heeled' can be an answer for 'mended' (heeling is a kind of mending). I'm unsure of the 'a shoe' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for heeled that I've seen before include "Played the part of a hooker" , "As shoe may be repaired" , "Be well shod thus to have money" , "Leant over" , "listed" .)
