squeeky shoes

I know this is not related to any foot ailment, but I thought you might have an answer for me since I remember reading somewhere that there is something I can do to fix this problem. They are a brand new pair of shoes and it is quite annoying and embarrassing to walk with squeeky shoes. As I said, they are quite expensive shoes and I have only used them 4 or 5 times.
Thank you for any help you can give me. Camille Ascoli
