It's my civic duty to tell you that Pure Citizen is having a sale on Cri de Coeur / Hearts of Darkness stuff. If you have memorized all of the shoes I own, you will know I own and love the Slims. (Flat, comfortable, cute.) CDC is made in a sweatshop-free factory in China and is an all-vegan brand.
There are also heels on sale if you like that stuff.
From their site: "The Collection consists of the highest quality vegan materials – including Ultrasuede made from recycled plastics, eco-PU that’s low-VOC, breathable and biodegradable, organic cotton, hemp and reclaimed wood and is committed to choosing vendors who abide by our ideals of earth-friendly manufacturing processes and fair treatment of workers."
