These are a size 38(7.5) but I'd say fits more of a 7 because they are made to fit snug on your foot, like being barefoot. They are Earth Grounding shoes. I bought them at a shop on a meditation retreat. I just have narrow feet and the wider toe doesn't work well for me. I only wore these once and they are 100% leather, Navy suedewith a shimmery brown distressed leather.
