Feet with a high arch or instep while standing, are symptomatic of a foot condition called pes cavus. The arch, or instep, runs from the toes to the heel on the bottom of your foot. Pes cavus is the opposite of flatfeet (pes planus). Pes cavus is less common than pes planus. Pes cavus usually occurs in both feet and at an early age. The sudden appearance of the pes cavus, or if it appears in one foot only, may be the result of trauma or a neuromuscular disease. Pes cavus may be initially asymptomatic, but often becomes progressively symptomatic with age. In general, pes cavus is a more bothersome foot type than a flatfoot. Less of the plantar surface of the foot is weight bearing resulting in increased stress on the heel and the ball of the foot (metatarsal heads). Associate with high arch is, Gait cycle, Overloading of metatarsal arch due to structural imbalance, contracted muscle/tendon structure,over exaggerated arch and non weight bearing, overloading of calcanus bone due to structural imbalance. Causes include, Hereditary,abnormal walking gait,footwear, neurological disorders. Symptoms include,Forefoot pain – collapsed metatarsal arch/forefoot calluses, Contracted and twisted digits (hammer toes), General mid foot pain (longitudinalarch),Heelspurs syndrome (plantar fasciitis), Achilles tendonitis and calf pain.
