Is AUTHOR wrong in the post ? POST : So, in my friend group a lot of us like basketball shoes. I had some Jordan 3's that my friend (I'll call them aaron) really liked and wanted.
 He came up to me at school one day asking if i would be willing to trade them for soldier 11's which he knew i loved. I told him of course and that Saturday we had traded. I come to school Monday wearing them and find out that they're actually not Aaron's shoes and are some that he borrowed from another friend(I'll call them ashley). ashley says they want their shoes back and I say that I'm willing to return them but I'll need my shoes back.
so the next day I come to school wearing different shoes with the soldiers in my backpack. I go to Aaron for the shoes and the Jordans are muddy AND THE SOLES ARE MISSING. so I say i'm not giving the soldiers back until He gets me a new pair of 3's. 
since then I have been completely shut out of the friend group and getting spammed with texts from our whole group saying that I'm a dick and that i shouldn't have traded with Aaron if i wasn't willing to risk the shoes being destroyed.
so... AITA for not giving the shoes back?

TL;DR: i trade shoes, mine get destroyed, I'm not giving theirs back
