I may have. I got a couple pairs of Montrail Molokini's on Zappos.com and another pair on ebay. Zappos is a little expensive, but they arrive very quickly and have a great return policy.
The Molokini's are different from most flip flops, because you heat them for just a few minutes in the oven, wear them for a few minutes, and they form perfectly to your feet. You can see every little print of your toes on the footbed. (Yes, I'm not kidding, you heat these flip flops in the oven

). When I got my first pair they were so comfortable right out of the box, but I decided to prepare them as the instructions said. My mom swore I was going to ruin them. Oh, my God, after heating them and then wearing them, they were even more comfortable. I wore them straight out shopping and my feet felt so good and my arches so supported, that as soon as we got back my mom insisted I order her a pair. The whole time she was saying she couldn't believe she was paying that much for a pair of flip flops and they had better be good. Well, since I was ordering her a pair, I had to of course order me another pair.

When they came, she said hers were perfect and she didn't think they needed to be heated. I talked her into it, but as I was putting them in the over, she had a very panicked look on her face and was warning me I had better not burn her shoes. Afterwards the look on her face was priceless. She immediately demanded that I order her another pair. I made her wait a couple of weeks to make sure she still liked them, then I won us both another pair on ebay. My mom is a 74 y/o diabetic with very bad knees, who is very particular about her shoes. She wore her Montrail Molokini's all winter in the house and as soon as the weather started getting the least bit warm started wearing them outside. Personally, even though I love the Molokini's, I still wear my Teva Mush more, but my mom prefers the Molokini's over the Mush. If you do a search on line for Montrail Molokinis you may be able to find them cheaper than Zappos. I haven't really seen that many on ebay, but last fall there was one seller that had them.
