I got these in a store. I usually wear a 9 and sometimes a 9.5.  I tried on the 9 and it was pretty much perfect, but I thought I'd try on a half size bigger just to check, since I often get 9.5 in sandals as I hate to see people's heels hanging off.  I saw that they didn't come in half sizes and knew I wouldn't need a 10.  The nine is definitely true to size on me.
As soon as I tried them on I had to get them because I am all about comfort (but not looking old ladyish(sorry, old ladies ;) )nowadays.  The straps hug my feet well and they are comfy to walk in.  I just got them, so I'll update it that changes.
I got the black/pewter and if they work out as well as I think, I'll get the other colors, too.
