This review is written for those looking for a sport sandal for a narrow, skinny, low volume, small-boned foot with long toes and a high arch.  My foot is 10 1/4" exactly. Yes, I'm a freak. Not really-see the pics I posted. I normally wear a 10M in regular shoes and have trouble with slipping in the heels with some styles.

I really like the arch support in this sandal. It's better (firmer/higher) than any I've tried. That's not to say that it is HIGH, just way better than others. Because the non-adjusting heel strap allows my foot to almost slide out of the strap in back when I walk, I'm going to try these a full size down (9) and see if I get a better fit. I'll come back and edit my review for fit, comfort, durability and potential tightening strap (strangled big toe) issues once I've tried them. Other reviewers say you need to get these dirty to keep the strap from tightening by itself. We shall see!

I got the color they call "Impressionist" on this ordering page. On REI's site, they call it Diamond Row, which just refers to the diamond print on the straps. The box says "Rouge" AND Diamond Row. It is more red than I think it appears in pics. See the photos I uploaded.

Edited to add: The picture and color description on this page has changed. What they were calling Impressionist is now called Diamond Row here (should say "Rouge"). It does look red, just as I said, right?  The impressionist shown now that is purply is new; I haven't seen it before. I did try these a whole size down and Eureka! They fit! The toe does tighten up sometimes, but honestly, I think that may have more to do with my tendency to try to slip my foot out of the sandals without undoing them and then trying to slip them back on. I think it pulls things out of whack a little. I don't find them hard to re-adjust, though. I'm really pleased with these. I can go for long walks in them and my feet are very comfortable.
