Size US 10 / 43, UK 9 Leather: Oro-iginal Leather Last: 23 - The last is the form used to shape the interior of the shoe. Outsole: Traction Tred Cushion Crepe Wedge Am sure you guys know these a great pair of boots that will last a long period of time. Reason for selling; This pair was purchased to hedge my bets against sz9 being too small. It turns out that sz10 is both too big, and still not wide enough. + Original Box + RedWing insoles, purchased in Japan + 1 application of Obenauf LP's on day of purchase, 1 application of RW Mink Oil applied when cleaning for sale.
