I have never seen them in person so I didn't realize they ran so narrow. I don't think all their styles seem narrow though. They have many different cuts and lasts. The square toe flats specifically are noted as being good for broad feet.
I wear Superfeet insoles in all my flats now, so cushioning is less important...and even less desirable in a way because a flatter sole leaves more room for the insole.
Anyway, the sizing is interesting. They have 2 size charts: one for broad feet and one for narrow feet. Each style has its own size chart, and most are quite different from what you might be used to. For example, I clicked on the broad foot sizing chart, and was told that I should wear a Euro 39 in the low cut style, which is 2 sizes up from my usual size. The only real difference between the broad and narrow size charts is that the broad size chart shows everything a size or two larger. I'm not sure how that would affect the length though. All of the styles are meant to fit snugly initially, but eventually mold to your foot.
I think the idea of having no left or right foot is genius. I wear Indian khussa shoes around the house and they are just like that. Initially they are very snug and awkward, but soon they take on the shape of your foot, which is so much better than having a predetermined shape that doesn't have anything to do with your individual feet.
