Upper: Genuine Leather Insole: Genuine Leather Midsole: 6mm High-density Memory-foam Outsole: Non-skid, Non-mark Rubber Leathers: Gold Certified by Leather Working Group Very gently used. Personally owned and tried to break in, never worn outside. I decided to go with a different size. To me they run a little small. For reference I am usually a 40 in brands like Dansko and these are a size too small. Will probably fit a size 8 or 8.5 best.
