What should i do with my new Zoots that rub blisters

Here's the deal....

I ordered a pair of Zoot Ultra TT running shoes from Trisports.com a few weeks ago.   They were on back order so i had to wait for them.   I then went to the NYC Marathon Expo (before i had received the shoes) and bought a new pair of the same shoe....but the new 2009 2.0 model.

So when i get home i have my new pair i bought in NY and the pair i had ordered waiting on me.    Since the money was already spent, i decided to go ahead and keep the pair i ordered for a spare pair.

I've done several runs with the 2.0 pair i got in NY and like them alot.   They are comfortable, don't rub, and are nice without socks.  

I then decided to try out the other pair and went for a short 2 mile run.   I wore those with socks and they tore my feet up.   In just 2 miles, it wore a big blister on the inside of my big toe....i found that very odd.   It also rubbed a blister on the heel of my left foot.   I haven't worn them a second time.

So i call Trisports.com and naturally they won't take them back since they've been worn outside.   So i'm unsure as to what to do now.   Do i try to wear them again and maybe they don't rub like they did before?   The heel doesn't worry me much.....but the inside of my big toe?   That is really uncomfortable and somewhere that shouldn't get blistered....with socks none the less!!

Or should i give someone here a great deal and sell them?   I'd really hate to do that because i really like 'em and they are comfy.   I really really like the 2009 pair better, but these are nice too.....minus the blisters.

Any ideas on the blisters i'm getting on my toe?
