I wouldn't say that I am afraid the rock them, but interestingly enough most of my shoes remain deadstock for 10+ years. I usually try to double or triple up on the ones that I like, thinking that I would rock a pair. However, this strategy never fully worked because at some point my daily rotation grew so large that I never get a chance to wear the new additions.
To people who think it's dumb not to wear J's, here's a bit of perspective from a collector's point of view. As a child growing up who couldn't afford to spend $100+ on a pair of shoes, I always envied those who could. So when I became financially capable, I started collecting, as a way of capturing a missing piece of my childhood. I don't buy J's to rock the latest or the greatest, I buy them to, for a lack of better words, "look at". People collect a variety of stuff, from baseball cards to coins, from spoons to hubcaps, so why not shoes?
So, if you intend to on buying the latest J's to rock, great, but don't discount the collectors who appreciate these shoes for their design, history, and innovation through the years.
