I always buy Nike sneakers, but I'm not hard on my footwear. So I only need to buy a pair every 5 years or so.
When I got OUT of the Marine Corps, I still had the sneakers that I had in HIGH SCHOOL... not that I wore them all the time, but still... like 6 years later I still had em.
there was a major purge.
and now I harass my wife who likes to go shopping WEEKLY... every spring and every fall I go through her side of the closet and make a few piles on the bed and make sure the tags are showing on the stuff she bought but never wore....
and we purge.
