Mechanics: You may have plantar fasciatis.. I suggest you see a podiatrist.

More support: Try more supportive shoewear or inserts. If still a problem, see a podiatrist.

Multiple: Factors: what type of shoes are you wearing. Avoid flats and stick with shoes with good support. Do your feet pronate? Or move in to a flattened position when standing? Better to wear arch supports.
