One for One

So recently, I bought a pair of TOMS. Not to be a cool hipster-type college student, but because I really think the cause is worth the 50-ish dollars I paid for them. I'm not sure how I feel about them yet because I have not worn them out in public (I work at a summer school- I don't want the kids to ruin them!). The website says that if you wear a size 10, you should order a 9 1/2. I got a 10 anyway because I'm pretty sure that I'm a 10 1/2 in real life.

Here are some things I'm worried about:
1) they will smell bad after wearing them and Sean will make me throw them away
2) they won't hold up long enough (1+ years)
3) my TOMS will hurt my feet

If my feet end up smelling/causing the shoes to smell, would foot powder solve that problem? I'm willing to try anything. I had these really awesome shoes when I first met Sean (and I mean, I really loved the heck out of them) and they were Keds/flats. They smelled horrible and made my feet stink hours after wearing and one day Sean threw them away. Bastard. I also really want my TOMS to last and be comfortable because Sean and I are having a bet. He's betting they suck and aren't worth the money and refuses to buy a pair- no matter who is benefiting from it. I'm betting that they are as comfortable as everyone says and... well, I think it's obvious how I feel about "one for one". Sean is one of those types who feels that if anyone else likes it, he definitely AT ALL COSTS must not. It's very frustrating sometimes, honestly.
