Coins can be attached to the soles of your feet, and it is best to use strong double-sided tape to prevent them from dislocating or falling when walking.

Then you can put on your socks and be careful not to drop coins.

Socks can be worn or not, depending on personal preference, as long as the coin is tightly fixed on the Yongquan point at the foot. Stepping on coins while walking will massage Yongquan point and help you lose weight. It's just that coins may get beriberi.
