Thank you for looking. Manufactured in 2010, discontinued model. REDWING made in USA 2906 6-inch Lineman Boots. Last is NO8 last, size 8 D width, cowhide oil slick leather, Goodyear welt construction, Traction Tred (crepe sole). I bought these at a shop under the elevated train tracks in Ueno when the Lineman boots were first released. (I don't remember the shop name, sorry...) I feel the leather quality is different from recent Lineman boots. Although they are quite old, I have occasionally maintained them with mink oil. They have not been worn enough to require a sole replacement, so they are still wearable with the original sole. If you have any questions, please feel free to comment. Thank you for your consideration.
