The arched middle portion of the foot (6)

I believe the answer is:

instep

(Other definitions for instep that I've seen before include "Upper surface of the foot" , "Part of foot between toes and ankle" , "downtrodden area" , "Marching together correctly" , "Part of foot/shoe" .)

I've seen this clue in the Sydney Morning Herald.
