But whether you're running, walking, or standing on your feet all day, thinSOLE helps improve your overall foot health and comfort.

Do you experience a sharp stabbing sensation under your foot, especially in the morning?

Plantar fasciitis is a common cause of pain in the arch of your foot. It occurs when the tissue that supports your arch (plantar fascia) becomes inflamed. This can lead to pain, especially when taking your first steps in the morning or after long periods of standing.
