With prominent bones, the pressures often increase beyond tolerable levels. As the arch raises, the forefoot and heel migrate to the inside, the ankle tends to shift and roll to the outside along with rotating away from the body. The body weight that used to be balanced through the middle of the foot is now shifted to the outer edge of the foot as the arch raises. The ligaments on the out side of the foot and ankle pay the price after frequent sprains or by the severity of the sprain. Occasionally, there are torn ligaments or even broken bones following a severe ankle twist.
All sprains are painful and take several months to heal.
These are preventable with the proper bracing especially since individuals with CMT take longer to heal and since these injuries can cause an increase of certain CMT symptoms. The foot, ankle, and leg have a relationship to maintain balance. Once any deformity begins, it starts robbing one from proper balance. The body starts compensating to maintain balance. All deformities detract from the security of the foundation to support the body above.
