Due to the bunions I wear sizes anywhere from 9W to 10M and 9.5 according to the chart, with width between M and W, so because some reviews stated these run large, I ordered the size that fits me most of the time - 9.5 M. The shoe is true to size; well perhaps on a looser side, but the strap holds it very well.

I had to move the buckle pin the last available hole. This is why I took off one star, because I definitely have low instep and this shoe will most likely not fit a person with a higher instep. When I tried them on bare feet and walked around the home, they felt really great.  I usually have to break the shoes in while wearing at least pantyhose, but this was unnecessary with these sandals. Hopefully they will feel good even when my feet are a little swollen from summer heat or whole day wear.

I will update my review after having a chance to wear them for a longer period.

May 12 update: they are indeed very comfortable, but the bunions do spread the leather strips apart on the inner side.
