These have only been tried on at home. Note the very small mark on one shoe. It is hard to see so I circled it. See last photo. Say hello to our newest take on the ballet flat... - now with a modern square toe and super-comfy, scrunchy silhouette that fits your foot perfectly. With a comfortable, flexible sole you love, this one is made with luxe Italian calf hair. This leather was sourced from a tannery that's certified by the Leather Working Group (LWG), an organization that works to promote sustainable environmental practices in the leather industry.
