Personally, and like most reviewers, I think these run small. Order half to whole size up. Excellent used condition! From the manufacturer: The one shoe that elevates any outfit—anytime. Our sleek pointed-toe flat in black combines exceptional comfort with versatile, washable style. And It's knit from plastic bottles. DETAILS Soft, flexible upper in black—which means no break-in period, ever. Comfortable insoles and durable outsoles in black. Fully machine washable, so they're like new again and again. Our shoes don’t stretch much—so make sure they are not too snug.
