I have two pairs and I love em:
I wore my Odyssey shoes while playing golf in China and when I got done with my round I thought 'hmmm, something is not right here.' And then I realized that my feet did not hurt. It is true that I did not walk quite as far as a normal round since I had a cart but they did have cart path only rule so I did walk pretty far...
Anyway I can walk a long ways with no foot pain and my back does not hurt as much either...
Wish I could find some over here in Germany. My feet are killing me lately. ;(
