None of my Nike, Jordan or Adidas shoes do it. I've had shoes squeak before when I was younger but none of my newer shoes do it. *knock on wood*
What model of shoes are they?
I just got some Jordan Big Ups for ~$60 and they are damn nice. Also got some Kobe VII's, KD IV's, AF1's, some other airs, 2011 Hyperfuse, then my favorite Adidas Superstar II's.
It is pretty ridiculous what shoes are priced nowadays. I love Chuck's for weight lifting, but $40 for some canvas and a sheet of rubber? You have to be kidding. Oh well, supply and demand.
Kobe VII's are amazing btw. IMHO of course.
I prefer Asics for running shoes.
