Stand with your feet facing forward and use a straight surface like the edge of a rug, a wall, or a yoga mat to align one foot and then the other so that the feet are facing straight forward. This may feel strange at first. Try to adjust your foot position whenever you can remember. Schedule some time at home to walk around barefoot. This can increase foot dexterity and stretch the muscles. Sit with your legs strait and your feet flat against the wall. Place a pillow underneath your buttocks. Lean forward with your back straight. Hold for 10 seconds. Rest for 10 seconds and repeat 3 times. This stretch is especially important for people who wear high heels. Lie on your back with your buttocks a few inches from the wall. Place your legs in a "V" and straighten them. You should feel a stretch in your inner thighs and your arches. Lying with your feet elevated above your chest can also help to reduce swelling. There are a few easy moves that can help stretch your toes and provide relief. Try curling your toes around a pencil so that they can hold it up. Hold this pose for a few seconds before releasing the pencil. You can repeat this 2-3 times. You can also try picking up small objects like marbles or markers. Sit down and put your right foot over the top of your left thigh. Place the fingers of your left hand between the toes on your right foot. This helps to widen your toes and stretch them. Do this stretch for 1 to 5 minutes, and then repeat it on the opposite side. Rub sore feet with a topical gel that contains an anti-inflammatory aid. The act of rubbing feet may also relieve muscle tension. Treat foot soreness with the Rest, Immobilization, Cold, and Elevation (RICE) method if your foot pain is acute. Rest your feet when they start to hurt. Place an ice pack or a bag of ice wrapped in a towel on the most painful parts of your feet and wrap them with a bandage or towel. Elevate your feet so that they are above your heart in order to reduce inflammation.  You can also try the Movement, Elevation, Traction, and Heat (METH) method. While RICE helps reduce swelling and pain, METH can increase blood flow and promote healing.

Summary:
Align your feet. Walk barefoot with good alignment. Do a straight leg stretch. Do a V stretch. Pick up small objects with your toes. Use your hands to stretch your toes/feet. Use a topical gel. Implement the RICE method.
