So I didn't realize that these were made of a canvas type material but it doesn't even matter because they are some of the most comfortable shoes I own. If you need cushioning under your feet for support, these might not be the shoes for you as they are essentially like a flat sandal. However, they don't rub my ankles raw and the toe box isn't tight on my foot. After reading the other reviews, I ordered a size up (I wear a 10) from what I normally wear, so that could be why they're so comfy.
