The Xero Shoes Glenn City is a refined men's dress shoe that pairs barefoot freedom with polished, office-ready style. A premium leather upper and clean stitching sit atop a flexible FeelTrue rubber outsole — so you get the look of a traditional dress shoe with the ground feel, zero-drop posture and foot-shaped toe box Xero is known for. Backed by Xero's 5,000-mile sole warranty.
