Upper fabric is printed canvas, featuring 3D eyeball detail and a synthetic rubber sole. New to Chocs? 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; if you're an AU9 that's occasionally an 8.5, then size down to the US8/AU8.5/VZ38. If you're already a fan and are adding to your collection, refer to the VZ size printed on the bottom of your shoe in a cute little love heart, and simply choose the same VZ size when ordering; for example if there's a 37 in your love heart, then choose US7/AU7.5/VZ37. Easy peasy!
