Printed canvas fabric upper and synthetic rubber sole. New to HCD sneakers? Choose the size nearest your most-often purchased AU size – for example if you are usually an AU9, sometimes 9.5, choose US9/AU9.5/VZ39. The new sneakers range runs a little more narrow than our other flat shoes, so if you consider your feet to be wide and/or you wear your Mary Janes on the snug side, you may want to size up.
