1. Wear thick socks: Wear a pair of thick socks inside when wearing shoes, and choose shoes smaller than the original shoe size. Although I was not used to it at first, as long as I keep wearing it, I will get used to it later and my feet will become smaller.

2. Wear small shoes: If you want to make your feet one or two yards smaller, you'd better wear shoes smaller than yourself. It may be a little crowded at first, but after a long time, I won't feel it and my feet will become smaller.

3. Soaking feet with hot water: Soaking feet with hot water often can make feet look thinner, because hot water can accelerate the metabolism of feet through the skin epidermis and help discharge waste and excess water. Therefore, it can make the skin of the feet firmer, thus achieving the effect of thin feet and making the feet one or two yards smaller.

It should be noted that these methods may take a long time to see the effect and need to be adhered to. At the same time, if your feet are too big or too small, it is recommended to consult a doctor or a professional to determine whether there are other health problems.
