Black leather side-gore boots with a back zipper design - Color: Black - Design: Back zipper - Material: Cow leather - Style: Zip-up boots Thank you for viewing. Japanese Padmore zip-up boots, size: 43 Vibram soles have been applied to the leather soles, so you can wear them without worry even on rainy days. For reference, I usually wear size 28 in Nike and Adidas sneakers, and 27.5-28 in leather shoes, but these have a little extra room and are not constricting, so I could wear them comfortably for long periods of time.
