Movement of a runner whose foot rolls too far inwards and puts a strain on the muscles, tendons, and joints of the lower leg. Over-pronation may be due to anatomical abnormalities or it may be caused by shoes that tilt the foot inwards. Over-pronation can be diagnosed by looking at the wear-pattern of well-used shoes; it increases the wear along the inside edge of the shoe. In normal runners, wear is greatest on the outer edge of the heel, under the ball of the foot, and at the front of the sole.
