Avoid walking barefoot even indoors. Use appropriate sized sandals/shoes with arch support, soft sole and heel raise. Try losing weight if you are overweight/obese. Soak your feet in warm water if your soles are hard and apply moisturizer to the hard margins of the sole. Perform plantar fascia stretching exercises using a towel/tennis ball/frozen water bottle. Apply pain relief spray. Video consult with me if you have any more doubts.
