Expert fit notes

The Stan Smith can feel about half a size small — the leather upper is firm and the last is on the short side. Many wearers start by checking half a size up from their usual US size, or a full size up if they prefer a relaxed fit or wear thicker socks. The shoe stretches slightly with wear but starts snug, especially across the toe.
