I bought these shoes about a month ago and they're just not working for me - one is perfectly comfortable, the other sits oddly against the back of my foot. They look identical to me so I assume it is a problem with my feet, not with the shoes (and I've had the same problem with other shoes before).
These are a women's size 10 and only a tiny bit worn since I haven't had them for very long. They're
very flexible, a great choice if you're into that barefoot running stuff or just a comfy walking shoe.
