JBU by Jambu Women's Polaris Boot Black A simple waterproof slip-on boot with size zipper closure, the Polaris draws inspiration from slouchy ankle boots and moc-inspired shoes for a finish that is casual and fit for anything. A vintage vegan leather construction adds a beautiful distressed look to the boot, while simple petal-inspired perforations add a hint of flirtation to the otherwise rugged style. A thick rubber outsole provides all-terrain traction, while memory foam insoles offer all-day comfort. JBU by Jambu Women's Polaris Boot Black
