Cavus Foot Insoles

About

Cavus foot is a structural condition in which the arch of the foot is abnormally high, causing the foot to bear weight primarily on the heel and the ball of the foot rather than distributing load evenly across the entire sole. Unlike flat feet, where the arch collapses under load, a cavus foot maintains its high arch even under full bodyweight, which means the foot's natural shock-absorbing function is reduced. The result is increased pressure at the heel and forefoot, reduced contact area with the ground, and a foot that is less stable and more prone to ankle sprains. Common associated symptoms include heel pain, ball-of-foot pain, claw toes, and general foot fatigue. Cavus foot can be present from birth or develop as a result of a neurological condition, and it may affect one or both feet. How insoles help with cavus foot Arch filling and pressure distribution Because a cavus foot's arch doesn't contact the ground, all bodyweight is routed through the heel and the metatarsal heads, creating intense pressure at both ends of the foot. An insole with a contoured arch fill that matches the foot's elevated arch provides a contact surface beneath the arch, redistributing some of that load across the midfoot. This reduces the peak pressure at the heel and forefoot and gives the foot a more stable base, as more of the sole is in contact with a supportive surface. Heel and forefoot cushioning With load concentrated at the heel and ball of the foot, both areas need dedicated cushioning to absorb the impact that a normal arch would otherwise help dissipate. An insole with substantial cushioning at both the heel and forefoot zones is particularly important for cavus foot, as the foot's reduced contact area means each of those zones absorbs more force per unit area than a foot with a normal arch would. Lateral stability High-arched feet tend to supinate, rolling outward during the walking stride rather than pronating inward like a normal foot. This places excess load on the ou
