If they are leather try this: Fill shoes with scrunched up newspaper to retain their shape. Add 2 tablespoons of white spirit vingar to the same amount of lemon juice (freeshly squeezed). Pour together and add a cup of boiling water - leave till cold. With a soft sponge wipe over the out side of the shoes and leave to dry. Do this 3/4 times. Walk in the shoes...if sill squeeking...do again.
Wear a different pair of shoes. Women usually have more pairs than they need anyway.
