I wore my first pair of these out. They were navy white. They were amazing shoes and I noticed my posture improve and walking became much more fun. My overall health benefitted. Unforunately they wore out. So I replaced them with exactly the same ones ... only in navy/silver. I thought briefly about trying something different, but deceided to stay with the ones I love. I don't regret my decsion. The new ones are great. Once I got the new ones and put them on i realised just how worn out the old ones had become. The new ones look and feel great and I've been doing lots of walking. I love them, just like I did the ones I wore out.
