Burton DriverX snowboard boots BRAND NEW UNUSED! Size 9.5: MSRP $350, selling for $100! 2007 boots, ordered and never used as they fit too large for me; suits measured foot size US 9.5-10; mine are 9.0-9.25. Stiff, high-performance boots: freeride, carving, stomping power, and Vibram soles with aggressive grip for hiking. Selling cheap because I've been lugging them around for 4 years!
