UPPER: Matte black leather Leather laces Leather Lining INSOLE: Zero drop No arch support Soft cushion 1 mm Leather insole SOLE: 4mm Black Vibram Handcrafted, handcut shoes made by a small family business in Athens Greece. I purchased these ready-to-ship directly from the company website in October 2022. They are NOT customized and are a standard size 38. I wear an 8. I wore them once and found that barefoot shoes don't agree with my feet. They have been sitting in their box in my closet since.
