① New Ballet Shoes I usually wear shoes around 23.5cm. For pointe shoes, it depends on the manufacturer, but I wear 24 cm. My feet are thin with a low instep and narrow width. Size: 40 Because they run small, the purchase site advised to buy two sizes up. I bought them as instructed, but: The length is okay. The width is wide? The elastic is sewn on loosely. No drawstring. If anyone can use them, please do.
