Should I buy something to start collecting or is it just a waste?

I own 68 pairs of shoes (that still fit me 30 more if you count the ones that are snug), all from different events, stores, gifts, a lot of hard work as far as searching goes, and a lot more work as far as just getting people to sell them to me. I wear all my shoes, I even have a rotating pattern that uses the rainbow to make sure all my shoes see the light of day (unless its raining, than I wear my fillers). The other day I was browsing around a little place my friend and me know about downtown where this guy has shoes a little earlier than most people, and I see a pair of jordan 15s (http://www.hijordan.com/images/Jordans-15/air-jordan-15-retro-1.jpg) and I KNOW I would never wear them, because i dont really feel them, but I like them.

I would almost be perfectly fine with letting them sit on my shelf for ever just to show them off to people, but never sell them. Should I buy them?
