How to do yoga for heel pain
Roll an object under your foot.
While rolling an object under foot isn't necessarily a pose or movement particular to yoga, it often is used in yoga classes that focus on feet. It's a good way to warm your feet up for further work increasing your awareness of your feet and how you use them.
You don't need to buy any specific objects or sports equipment. You can use any sort of round, rollable object you have around the house, such as a water bottle or a rolling pin.
