I am becoming a fan of the Earth shoes brand, because I have a long, narrow foot and very high arch, and I also need metatarsal cushioning. Most flats have zero support, but these are good, not excellent, but my feet don't ache at the end of the day. The toe box could be a little bit wider, but they are fine. After walking around in my living room with them for a few days, I wore them for a 9 hour day of teaching and I had no blisters, no complaints except just a tad small, but they are being broken in. My only complaint is they are not as cute as I had hoped and I am wondering if I look a little matronly with them. The dark green color is cool, though, and somehow goes with everything in my gray, black, beige, white wardrobe. I wear an 11M or AA, and I ordered an 11M in these and they fit fine, maybe a little stretch needed in the right foot, for my issues.
