These are ZARA sock sneakers. The detailed sizing is shown in the fifth picture. I've only worn them twice, but the outside of my little toe starts to hurt, so my feet aren't wide, and those with wider feet might find them painful. The material is knit except for the sole, so there may be some fibers attached. Thank you for your understanding. As shown in the sixth picture, the toe area of the left shoe is a little dirty. They come with the original ZARA shoe bag, and I will ship them in a paper bag. Please purchase only if you don't mind this.
