When most people think Ostrich they think Ostrich leather with a quill pattern, not smooth Ostrich. For many years that is all there really was out on the retail market. The custom market was first to recognize the Ostrich Leg as a good leather to work with. First in tops and accents, then full vamps. Today there are several good choices available off the shelf known as smooth Ostrich. Smooth Ostrich is certainly smoother than full quill Ostrich but it is not really smooth. Depending on the cut, Ostrich leg styling can be subtle or more pronounced either way it is distinctive.
