Plantar Fasciitis (Heel Pain, Foot Pain) is a common, painful foot condition. Plantar Fasciitis occurs because of irritation to the thick ligamentous connective tissue that runs from the heel bone to the ball of the foot. Symptoms of Plantar Fasciitis may be worse early in the morning after sleep. At that time, the arch tissue is tight and simple movements stretch the contracted tissue. As you begin to loosen the foot, the pain usually subsides, but often returns with prolonged standing or walking. Night splints are worn to keep the heel stretched out while you sleep. This prevents the arch of the foot from contracting at night which helps reduce the morning pain. Sizing: Small/Medium Fits Women 6-10/ Men 5-9 Large/Extra Large Fits Women 10-15/ Men 9-13
