A question about the shoes for my interview with Hollister?

I have an interview with Hollister tomorrow, and I'm wondering what type of shoes to wear? I'm honestly not a fan of the Jeans with flip flops look, although I will wear them if they are necessary. However, the only ones I have are other brand names, and apparently they look down on that. I do have a pair of Vans though, will those work? However, they're black, is that bad since they don't sell regular shoes anyways? Thanks :) sorry if this is confusing, I'm just really nervous.
