I just wanted to update that I found the shoes in my normal size on Jildor. They shipped them promptly, and they were packaged well (looked like the box had never been opened, as each shoe was stuffed and individually wrapped). The shoes fit right out of the box, and were comfortable enough to wear out immediately, which I did.
The forefoot is a wee bit snug, but nothing that a few wears won't alleviate, and certainly not enough to make me hesitate to wear them (and unfortunately even slight discomfort is enough to make me avoid shoes at this point, so these really are comfy). I have higher volume, slightly wide feet, though I can usually buy and wear average width shoes. The tags on the inside of the tongue were a bit scratchy, but I will never wear these without socks or tights, so that won't be an issue.The leather is sooooo soft, and the shoes seem well constructed. They are flat-flat and have NO support whatsoever. That isn't an issue for me, and I actually really like shoes like this, but it might not be ideal for everyone.
Overall, I am very happy and will be happy to order more Ash shoes in the future if the styles are what I want. And maybe they will just need to loosen up a little, but there is no jingle in these whatsoever. The square rings LOOK like they should move, and I can forcibly move them if I try, but otherwise they don't move at all. I am delighted with this purchase!
