Gray suede material Purchased from a Korean shoe store. The size is listed as 23 cm, but with an insole, it fits a foot of about 22.5 cm perfectly. Used for a short time, 2-3 times. Although there are creases in the front from wearing them, there is almost no other visible dirt. Although not visible from the outside, there is some lint from socks inside the shoes. There are slight traces of sticker removal on the back of the shoe soles. Please check the condition in the images. The condition is good as they haven't been worn much, but please understand that these are used items before purchasing. Clean casual Traditional Korean
