Was unsure the size to order so I ordered my normal size. I've never worn this brand but came highly recommended for comfort. The reviews said they ran smaller & narrower we but that was not my experience. They were too long & wide so I reordered a 1/2 size smaller & medium width instead of wide. I liked the shoe style, cushion, flexibility & packability. I don't think they will even need to be broken in when first wearing them. Hope the new size ordered fits well.
