CushZ Slide Sandal (Women)

I bought this model of Chaco because I love wearing sandals in the summer, especially something that is quick and easy to get on and off. I was recently told by my podiatrist that I had flat feet and she recommended Chacos. When I saw this model it seemed like it would be a good replacement to my flip flops. I had no idea that this model was going to have such an issue staying on my feet until I actually attempted to walk in them. I took my dog on a quick walk around the block and now because they were worn ONE time, they can't be returned. I can understand this policy, but how can you possibly know that a shoe is going to be what you need it to be if you don't walk around in it? I really wanted this sandal to be everything I imagined it would be, but it turned out to be a disappointment.
