If you've got a soft spot for classics with a penchant for the uncanny, B2 has you covered with the Union Slingback. Putting a modern spin on a sleek silhouette, this pair features the usual signatures: a razor-sharp pointed toe, high-quality construction, and an adjustable slingback strap. However, the style stands out thanks to its translucent wedge heel, adding an optical illusion-inspired detail to the towering silhouette.
