I like the look of these shoes - perfect flat with lots of versatility. I bought a pair of Poppy Barley's because I heard from friends how comfortable they are. However, the placement of the back seam on the Left shoe is in such a place that it rubs a lot on the foot. I inspected the difference b/w the Left shoe from the Right Shoe and the seam is slightly to the outside of the foot on the Right shoe which is why there were no issues with that foot. I developed a significant blister on the left foot and needed to wear the shoes with socks for several weeks. That spot on my left foot continues to be irritated in this shoe. If the seam cheated out towards the outside a bit, I suspect this issue would be non-existent.
