These slip-ons from MOON STAR are made with breathable mesh material. They are the 810s model. I wore them outside only once, but I'm selling them because the size doesn't fit. My usual size is 25.5 cm, and they felt a bit large. I think they would fit perfectly or have a little room for someone who wears a 26 cm size. Please note that there is no box. - Brand: MoonStar - Model: VINIE - Color: Black/Gray - Type: Slip-on Thank you for looking. Color...Black系 (Black-based) Stains, tears, odors, etc...None
