Living the Dream
The misses and I have used NB walkers for years. She replaces hers more often than I do. I have a brand new pair in my closet now. The old pair are in rough shape, so time to get out the new ones.
One thing I love about NB shoes is there's no break-in period. For me at least they feel great from the start, no band-aids needed.
I replace my walking shoes when they wear out and aren't comfortable anymore. I buy whatever feels good. When I first get them I wear them in the house for awhile. Then for short trips to the store etc. When I'm sure I have a good fit I use them for walking and hiking. The old pair get used in my garden until they fall apart.
That's my strategy also. They end up lawn-mowing, string trimming, and tromping around in the mud, shoes.
