I need some help with quite an interesting issue.

Being new to any of this, I don't necessarily have any idea where to turn to. So, I figured I'd start here at least.

Back story:
I recently acquired a pair of Nike LeBron XIII Limited "Opening Night" shoes. These shoes are really cool and I already love them. The shoes have traded hands a couple of times and with that comes issues. And as anyone in a collecting market would know, issues generally affect the value and can be an annoyance.
 

The issue:
Receiving the shoes, they were a bit dirty, a bit scuffed and scratched, and worst of all (the reason I am posting this), I can't wear them because the insoles are gone. You may be wondering how I acquired a pair of limited LeBron XIIIs without insoles. They were given to me, as my brother (who received them from his friend) cannot wear them because they are too small for him. Being that I am a picky person about almost everything, I am now trying to search for the insoles that go to these shoes before settling with an off-brand insole. So if anyone has any idea how I can acquire the insoles for these shoes, then I would appreciate the help. Though I feel like I'm probably wasting my time, I would like to find out if it is possible first. Any help would be greatly appreciated. Thank you!

There are multiple pairs of brand new pairs on eBay UNDER retail. You talk about value like you're going to sell them but you won't get much for them. Buy some insoles and just wear them and enjoy them.
