Whats the difference between the fitting of this 2 shoe? I think the fitting is both for wide feet right?
Well, I can't really say the difference except that the 8500 fit better for me. The 8500 has this curve on the back that hooks onto the back on my ankle. And it gave me the secure feel I didn't get with the 9000. It's always better to try them on for yourself. Your feet are different than mine, so your experience may differ.
