My favorite of their current offerings is Neuaura's "Kaveri" ankle boot (pictured left in the grey). The boot has a slight 1/2" heel, making it perfect for walking, hardware at the upper ankle, and a bit of a rounded toe for extra comfort. The boot comes in the grey and a soft black. The grey comes with plaid insulated lining, and the black has the same soft insulated lining. Made from vegan-friendly pleather. $124.99; find them here.
For a taller boot with a higher heel, I like Neuaura's "Thames" dress boot. This boot comes in the pictured dark brown and black. It has a 3" heel and is made from the same vegan-friendly pleather as the ankle boot. It also has the same insulated lining, making it perfect for colder fall and winter months. $175; find them here.
Finally, for something a bit more trendy and less expensive, check out Vegan Chic's "Comfort Vegan Slouch Boot." The boots come in the left pictured black. They have a 2" heel and lots of straps. Like the above two, the boots have an insulated lining to combat colder weather. They are made from vegan-friendly pleather. $44.99; find them here. Also, if you aren't into a heel on your slouch boots, check out these of about the same price that have a flat sole.
