Maybe a decade ago, I bought a couple of pairs of these bottom of the line, New Balance walking shoes off the clearance table at The Sports Authority for under $10 a pair. I didn't need them right away and they sat in my closet for a few years. At first, I didn't like them because they required a break in period and I got sore spots on the back of my feet above the heel. After that, they were real good. These are the same shoes that I'm wearing in my picture on the right sidebar.
They have been virtually the only shoes I have worn now for six or seven years. They are starting to show some serious wear but they are still good. Some people believe that shoes like this should only be worn for a limited period of time and then discarded. Not me. As long as they are comfortable and hold together, I keep wearing them. I don't treat them special. Every six months or so, when they start to get scuffed up or the insides start to smell a little, I throw them into the washing machine with some detergent and bleach, then tumble them around in the dryer and they're good to go. Eventually, the soles delaminate from the rest of the shoe. Super glue won't fix that, I've tried with other shoes. I expect these shoes are about to go that route but so far, so good. These shoes have been the best and longest lasting, by far, that I have ever owned in my life.
I still have another identical pair, in new condition, sitting in my closet. If they are as good, my daily shoe needs will probably be met until I'm nearly seventy. After that, one more good pair of shoes will probably see me out.
