So I ordered the 6.5 and they were true to size - they fit like a glove.  Just amazing.  However, I know my old foot injury will swell after a full day on my feet at an event, so I opted to size up to a 7 and add the squishy metatarsal pads so that I don't wind up walking like a goat picking his way across footholds on a rocky slope after a few hours.  LOL

This works as it snugs up the shoe and pushes my foot back so that the heel doesn't slip.  If you have no issues with your feet, your regular size should be perfect.  Love the shade of gray.  It is more of a blue-gray (versus brown-gray) and is a fabulous complement to the white, aqua and royal blue dress I'll be wearing them with.  (I already have an aqua wrap/sweater to go with it, so I opted out of funky color shoes this time because I don't have the time or patience for matching right now.)

I also tried the taupe/tan shade (looked better right next to the sweater, but not as nice with the dress).

I will probably purchase more in additional colors depending on how things go.  So far I love them, but they haven't actually had to weather a road-test.  I'll try to remember to update after spending the day in them...
