Return them.  No wait.  Keep them.  Nah, maybe you should just return them.  On the other hand, keep them.  Return them.  Keep them.  Return them.  Keep them.  Argh.  Such a hard choice.  Decisions, decisions, decisions.  Better yet, order a size 6.5 and see what you get.  Or, go to the kids' section of www.adidas.com and order a 6.0 and see if what they send you matches what you already received.  Better yet, visit the womens' section of www.adidas.com and order a 7.0 to see how that one fits.  One of these 6.0's or 6.5's or 7.0's have got to fit you the way that you want them to fit you.  No doubt about it.  There's a 6.0 that'll fit you just right.  I think that the best decision is to take Samo's advice.  Contact www.adidas.com.  Usually, if you loiter on their website long enough, a "chat" window will pop up with someone that says 'Hi, is there something that I can help you with today?"  You should reply, "Yes." and then continue to share your story and pose your question.

But, before you do any of that, you should revisit the rules of this forum and introduce yourself properly.  As another member once said [paraphrase].."...we're good lot of mates here, but you gotta follow the rules.."

I order them when I was in US but now I am in Thailand. (adidas Thailand doesn't have online shop and no any shipping and doesn't even have Superstar shoes sell here. Poor me. Lol)
So all I can do right now is just ask anyone who wear Superstar in US 6 to post thier photos because I don't know where can I take my shoes to compare with.
But your answer help me a lot! I used to email adidas.com but they answer me divergently and not clear enough. oh and they take a little long time to reply my question.
but I just knew that there is chat in adidas.com. Your answer is help me a lot!!!
Thanks! I will try to chat with them and I just introduced myself. I really forgot that but yeah! I did it. Thanks again.
