I like the Old Navy ones. They are my favorite because they are comfy and they look good.
Our Old Navy went out of business last year and now the closest one is about 40 min away.
What I did is buy a couple pair in each size of the black. That way I have all the size here and can make a pair whenever I need to. When I start to get low then I just place an order online and it takes about a week to get them. I tell people that I can do special orders with any color of flip flops they want but I need a 10 pair minimum to cover my shipping.
