Flee the seller! Explanations below!

I received my shoes on 12 December. It seemed to me that there was a defect in the right shoe but ... I'm not too demanding. but we are on January 19 is just over one month after and there, the sole of the left shoe is completely off ... I'll opt for a refund or so a new pair. but if the news comes with the slightest defect is return and refund.

Moreover, the model I received is not the same as the one I had (US model of 2007) and that's a shame.

Update 22/01/15:
After contact with the seller, he sent me roses on the pretext that I spent 30 days of regulatory time limits for withdrawal and offered me 10 refund ... a shame.
I compared my "converses" with those of the seller in a physical store, there is no photo ... The ones I purchased are counterfeit here ... or are from defective series ...

So I invoked the guarantee Amazon AZ indicating that it was hidden defect. Article L211-1 of the Code of conso. Neither one nor two, Amazon customer service on top, the refund is in progress. Thank you Amazon!
