Oboz is lifelong love of the trail that enables our designers to create footwear that's remarkably durable, comfortable, and always worthy of the task at hand .. Oboz philosophy is simple. Design the kind of footwear that we'd want to wear. Oboz is shorthand for “Out of Bozeman.” The reason is pretty simple: they make burly hiking boots and shoes. Boots that are capable of handling any adventure. From the inside out—200g of Freeze Guard insulation and B-DRY waterproofing—the Sphinx Pull-On is ready for ice-laden mountain towns. Featuring waterproof oiled nubuck, a water-resistant medial zipper, recycled components, and a Vibram Arctic Grip A.T. sole made of Vibram XS Trek.
