Yea! The order came right when they said it would. Getting items from Amazon feels like Christmas. I got them yesterday and wore them right away. I'm so pleased. This is just what I was looking for. Light weight and comfy with a little support, and on sale, too. I read the reviews before buying and even after the comment on the footbed, took a chance.  I'm soo glad I did. I think it's a personal thing that depends on your foot shape. I wear a 6.5  and normally if there's no half size I would go a size up but I got the 6 and it fits very well. (I have short toes so there's pretty much room to the end of the sandal) The adjustable straps are great as I am a little wide across the ball and toes, yet have a narrow heel and ankle.  Thanks!
Update: 8/11  Just got home from the Doobie Brothers concert at Musikfest. After spending the last 2 days trekking around down there, I did have some discomfort. Not as supportive as a walking or running shoe, of course, but far more comfortable than a flip-flop. I think it was much cooler in the heat than the running shoes but my feet did sweat. I have heal spurs. I think a bit more arch support might be helpful for me. The nice thing is they form to my foot and stayed secure with the straps. I kept a really good pace down and back as I didn't drive but walked down there. I wasn't worried about them sliding off. After today, I lowered my rating from 5 to a 4.
