I got these in the white raffia, and they are very pretty and unusual. However, between the high heel, steep arch, and small toe box they were an excruciating fit in my usual 8 medium.  I couldn't even get them on to try without my toes screaming.  However, the 8.5 is much better, and not that much too long, so they probably run a little short for the size.  They also seem to have good arch support, so I think they will be a lovely shoe for work and summer events.
