Certain orthotic modifications can be used to encourage a more plantarflexed position of the 1^st ray. The most commonly used modification is the reverse Morton's extension as it allows the 1^st metatarsal head, which represents the 1^st ray, to drop into a more plantarflexed position. Another option would be ordering a minimal fill as this would lead to a more plantarflexed position of the 1^st ray within the shell itself. In addition, modifications which would discourage rearfoot eversion, which leads to dorsiflexion of the 1^st ray, would be helpful. These "anti-eversion" modifications include: medial heel skive, wide plate, and deep heel cup.
