I have a similar issue trying to resell a pair of Vans sneakers. I bought the sneakers on eBay to begin with and they keep pulling it down saying they are counterfeit! 

The shoes are 100% authentic, the model is current as listed on vans.com. It's ridiculous! I can scroll through the hundreds of Chinese listings and spot fake after fake but they don't seem to have a problem with those? 

I'm going to be closing my account once my last few transactions have cleared. eBay stopped caring about small sellers years ago.... Fool me once, shame on you; fool me twice....
