This is the opposite of flatfoot. When standing, the inner arch of the foot is high and above the ground. When the arch is very pronounced or there has been increased stress on the foot, symptoms can result. People with high arched feet can be prone to develop pain over the underside of the big toe (sesamoids), the heel, and the peroneal tendons or over the outer metatarsals. Having an abnormally high arch can increase pressure over these areas of the foot and can also be associated with decreased flexibility of the foot joints.

In some situations, the high arched foot can be due to an underlying neurological cause (spinal nerve conditions, Charcot Marie Tooth disease, peripheral nerve disorders, stroke etc). In these cases, muscle imbalance has resulted in the development of the deformity. These type of cavus or cavovarus feet frequently benefit from a rebalancing of the muscles and tendons to correct the foot.

right sided severe cavovarus foot
The same right foot after correction. This has given a plantigrade foot and a much improved gait pattern.
