Medial post

A medial post is a firm foam and/or plastic device that, when inserted into the rear arch side portion of the shoe's midsole, adds support and controls the excess movement of the rearfoot. The medial post is constructed to be harder and denser in order to prevent the heel from pronation. The number of medial posts found in a style of shoe or the density of the medial posts themselves depends on the severity of the individuals' inclination to overpronate. Medial posts are found in all shoe brands that manufacture shoes used for athletic activitity.
