These shoes are great!  I bought them after trying on a pair from friend. Super, super comfy...I sometimes wear them aroung the house instead of slippers! I got these at the begining of summer and have had them on almost every day and they still look new. They do, in fact, mold to your feet just like they claim! However, I've noticed that the foot impressions do not remain when you take them off; they spring back like a memory foam bed. They re-mold every time you put them on. I'll admit that with the pricepoint of $30.00 I prob. would not have purchased these if I hadn't tried them on first. I just don't usually spend that much on summer shoes, especially flip-flops. But, these are well worth every penny and I have since given away ALL of my other flip-flops and got of these in different colors!
Just a note to think on; while these are true to size I don't believe they would work for someone who has very wide feet. I do have long, narrow feet and often when I buy sandals the straps are a little to big...not much, but still a tiny bit loose. These fit perfect for me. I think they will work if you typically wear narrow or normal wideth shoes.
