Vtg Sherpa Lined Pull On Leather Boot Yellowstone Park Klondike Sergio Italy 44

For sale is a wonderful pair of very soft high quality vintage leather boots. They are super comfortable and stylish and are sherpa insulated with a Klondike Elastomere sole. They are marked size 44 which is approximately a US Men's 10.5. They are handmade in Italy and branded Sergio and also have patches with "Yellowstone Park" on the sides. I don't really know the story of where these came from originally as they were purchased from an estate. They could be a one-off made as I cannot seem to find any other examples like them. They are very well made and in good used vintage condition. The soles remain soft and flexible rubber and the leather is still very soft with no tears or cracking. Sherpa interior is clean. Please see the photos. Thanks for looking!
