Made from sustainably-sourced, biodegradable natural rubber, our women's flip flops are not only better for the environment, but as they are softer and more flexible than plastic flip flops, they are also much more comfortable. Due to the elastic nature of natural rubber, our flip flops are also more durable than synthetic flip flops, meaning that they are less likely to break. With proper care, your Sea Sense Flip Flops will last for many years.
