Remove the old inner sole by gently but firmly pulling to detach it from the shoe's bottom.

If the inner sole is stuck, use a flat tool, like a spoon or the edge of a credit card, to help lift it. Some inner soles are glued strongly, and others are not glued at all: take care not to damage the shoe when removing the inner sole.

Tip: Take note of any specific contours or shapes in the old inner sole that you may want to replicate. When buying a replacement, look for one which matches the old one.
