This is one pair in 【Gray】. I bought two different colors for my high school son, but they don't fit and he doesn't want them... Unfortunately, I'm putting them up for sale. The size is "45". The insole is about 27.3cm, so there's a little extra room. I think the inside of the shoe is about 27.5-27.6 cm. We do not accept returns to prevent switching and due to cost, so please check carefully before purchasing. I will ship them by compressing them to fit the post's thickness. Thank you for your understanding.
