Although the shoes arrived in non-original packaging, that's just a detail. I've been using the shoes for a week and I'm very satisfied! There's no need to "break in" the shoes in any way. You just put them on and go. Great comfort and convenience, even after all-day use. Since I have quite wide feet, I intentionally chose half a size larger, so I have a bit of extra room for my toes, which means my feet don't get tired like in, for example, Haix or service footwear. I genuinely recommend them to everyone.
