I don’t know how to soak the three together. Here are several ways to soak your feet::

Foot soaking in vinegar and water to treat heel pain

Take 1,000 grams of rice vinegar, heat it to a temperature where your feet can be immersed, and soak it for about 1 hour every day. If the temperature of the vinegar drops, it should be heated again. Generally, heel pain can be gradually relieved after about 10 days. After continuous soaking for more than a month, heel pain can return to normal.

Soak your feet in water with Zanthoxylum bungeanum leaves to relieve heel pain

Boil your feet with Zanthoxylum bungeanum leaves in water and soak your feet while they are hot. Soak your feet for half an hour for several days, and you will be cured quickly.

Blue brick and rice vinegar to treat heel pain

Prepare a blue brick (grey brick), a bottle of rice vinegar and a clean towel. Heat the green bricks on the stove and put them on the ground. Pour half a bottle of vinegar on them. Place a towel pad on the bricks and step on the towel until the green bricks are no longer hot.
