I usually wear 23cm shoes, but when I put in the included insole and wear thick socks, the instep feels a bit tight. I tried wearing them a few times, but I really want to wear them comfortably, so I've decided to purchase a different pair. Overall, they are slim and the shape is really lovely... it's a shame. There's room in the calves, etc. There is no deterioration. I will also include the special insole for height adjustment. I will offer a discount if you don't need the box.
