I am a trainer in a sock shop in Taiwan Province Province. Socks are the same regardless of size. Because stockings are more elastic. You can buy stockings with enlarged front and rear stalls, or socks with great elasticity. For example, bare ammonia material has high elasticity and good resilience. But socks made of bare ammonia are very good in China. There are several kinds of socks to make. If you wear it in a local sock shop, you can buy it. If you don't have it, you can buy a bigger file.
