Yep, sure did. It happens when the internal layers of the sole aren't flush against each other and they can rub/slide on each other once air/moisture gets in there. It makes no difference to performance.
Make sure you always remove the in-soles from the shoes after you wear them each time. V9s seem to soak a lot of moisture into the soles when you wear them and that's why they'll squeak more after tennis.
I had a pair replaced by Nike because they squeaked fyi. They agreed that shoes that sound like ducks quacking was not ideal and a manufacturing flaw - which have a guarantee for regardless of where you bought them.
