Color is dark brown. They are made of napa leather with a fleece lining. They are a 40 EU / women's size 9 / men's size 7.5. I am an 8.5 and the length fit me. Unfortunately I have high volume feet. These are for low to medium volume feet. Only worn once. Here is a review from Anya's: https://anyasreviews.com/be-lenka-barefoot-boots-review-winter-2023-collection/
