I don't even own 6 pairs of shoes. Now, my wife's shoes is another matter
When I was young and dirt poor, I would get one pair of cheap shoes in September that had to last me until the next June. By then, they were usually held together with black, sticky electrical tape. My dream was to have one pair of shoes for every day of the week.
I can go three weeks without wearing the same pair twice. Some of those pairs are 15 years old. (Tip - black wingtips never go out of style.)
Some dreams do come true.
When I was a kid, I got ONE pair that was a couple of sizes too large so "I would grow into them". After a while the feet would start to cramp (shoes were resoled time and again) and I'd get the next pair. When I graduated grade school, all the other kids got new shoes, mom shined mine and said "That will have to do - they LOOK new".
My parents sacrificed a lot. My kids can't believe it (that was in the 50s). You can bet I have more than one non-oversized pair now, but my mind still boggles at kids and their $100 Nikes.
