I agree with NDD on the GSG 9s, Had 3 pair of GSG 9s. Wouldn't use them for long walks. I use the pair I have now for when I mow the lawn. Used a pair of Rocky's (not sure which model) on a 14 miler in Haiti January 2004. I wish I had them during SFAS. No problems, no blisters, lightweight, and comfortable. I will have a pair of Oakleys when someone gives me a pair.
