Material: Front suede, orange brown; back genuine leather, dark brown. There is a zipper on the back. Comfort: The heel height is 4cm and the front is 1.5cm, so while you feel the height, they are easy to wear and gently hug your feet. I washed the insoles, but some light stains remain (photos 17-18). I wiped the rubber soles and heel parts with alcohol, but the dirt did not come off completely. Photo 10 shows the suede on the toe of the right shoe is white. There are stains on the inner elastic of the left shoe in photo 12, stains on the inner toe of the left shoe in photo 13, and stains on the heel of the right shoe in photo 19. These are used items, and the suede parts have only been brushed, so I believe there are some unnoticeable stains. Thank you for your understanding. The boots will be packed with paper inside, then bubble wrap, plastic, and a recycled cardboard box, and shipped via Mercari delivery. Immediate purchase is welcome!! Thank you for looking.
