Like new Birkenstock Montana - dark grey/black - size 43 (Mens 10). Worn once - a tad too big for my foot but they look great. High quality thick leather, will last a long time. Currently selling for $170. https://www.birkenstock.com/us/montana-natural-leather-oiled/montana-heritage-oiledleather-0-pumontana-u_449.html
