The larger Anthro sandals were too big, and after all the commentary and a re-try-on of the smaller pair, I decided they were just too close for comfort, so both pairs went back. I am now on the hunt for a fun pair of 2 / 2.5 inch block-heeled sandals!
JCrew is currently doing 30% off $200+, so I ordered the high-waisted crops. We'll see if I have better luck with them!
