Diarist lifting foot smoothly (6)
I believe the answer is:
evenly
'smoothly' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for evenly that I've seen before include "In equal proportion" , "on an equal footing" , "avoiding hiccups?" , "Calmly or equitably" , "impartial manner" .)
