PLASTICANA's shoes are manufactured in France from hemp plastic. The Opana Mule is a contemporary and sustainable take on a classic style. They feature an easy to slip on and off form that is ideal for wearing around the house or on the go! The unique color comes from the sugars present in hemp. All of our PLASTICANA shoes are unisex, waterproof and 100% recyclable. Our Opana Mules are made in European sizes. Though we sell this shoe as Unisex, the sizes are EU Women's. This style runs mostly true-to-size. Please refer to the guide below. *Our next restock will include updated sizes to align with the "combined" sizes shown in the size chart.
