I exchanged the first shipment because the shoes were too narrow (I usually wear medium).  However, after 4 months I find I cannot wear these attractive-looking shoes. They have a stiff heel which makes them cut into my foot.  The soles are not flat, so the shoes rock which makes them not stable.  In addition, if I am wearing socks, they tend to move down under the foot at the heel.  If I could return them, I would.
