These are Converse Run Star Hike sneakers, a South Korea exclusive. I bought them about three years ago and wore them for about six months. I didn't wear them daily, but rather for short periods when going out. The rubber sole and laces are a bit black, but I don't think there are any other noticeable stains. Also, the size is 23cm, but the construction seems to be a bit large, as I usually wear 23.5cm in other sneakers. Thank you.
