You won't wear a consistent size in Choos. They are all over the map, even with similar looking styles. I have several pairs, around 50% I had to size up 1/2 size, 5% size up 1 whole size, about 40% true to size and rarely have I had to size down 1/2 size. Sandals, closed toe, flats, whatever, I have not found a pattern. My personal preference for high heeled sandals is to have my toes completely on the sole, so depending on the shape of the sole, I will size up more consistently with these. Choos tend to be more gently tapered than having a generous rounded sole at the toes for sandals. Boutiques and large department stores have the best selection for trying on. I have ordered some from
Nordies online and found that their comments on sizing (they indicate whether to size up 1/2 size, whole size or no comment for true to size) are accurate for any that I've ordered, so you could try here since you are in a small town.
