I think it's easy to see a difference? The internet shoes are exactly the same and it is the black rubber between the white sole and leather I'm talking about. But it's also when I wearing the shoe I can feel the difference.
I've got the Nike Free Inneva Woven SP. But i feels weird to walk in them and if I looks at the back of the shoes I can see some little difference between the sole and the leather on the left shoe (see the picture below). It's this normal/anyone have this "problem"?
This one is from the net...
