2. Wrong step
Some people may have an irregular tread, and this causes changes in walking, in addition to pain on the inner or outer side of the foot. In the supine step, the foot is inclined towards the outside, putting pressure on the last toe, while in the pronated step, the impulse comes from the first toe and the step is turned towards the inside of the foot. The ideal is to have a neutral tread where the impulse of the walk starts in the instep of the feet, so the impact is distributed evenly over the surface of the foot.
What to do: if there is pain, ice packs for 20 to 30 minutes 3 to 4 times a day is a good way to relieve pain, never put ice directly on the skin. Consultation with an orthopedist may be necessary in cases of ongoing pain, treatment may include the use of special shoes or physical therapy. See also how to choose the right shoes for running.

The formation of the bunion is gradual and in the first stages it may present pain on the sides of the feet.
What to do: if the bunion appears, there are exercises that can be done, in addition to the use of more comfortable shoes and devices that help to separate the toes, giving more comfort to the day by day, if you suspect swelling, apply ice packs for 20 to 30 minutes 3 to 4 times a day, without the ice touching the skin directly.
