Help me translate this, please

[jangoux]

So, I need to find in google something but i dont know the name in english. My daughter was born with a shorter hip and before the surgery i need something to compensate for the shorter leg. How do you name that thing that stays between your foot and the shoe, inside the shoe? In portuguese, it's palmilha and google translate it as sock.

An "insole" perhaps?
