Symptoms of this condition
The arch of a cavus foot will appear high even when standing. In addition, one or more of the following symptoms may be present:
Hammertoes (bent toes) or claw toes (toes clenched like a fist)
Calluses on the ball, side, or heel of the foot
Pain when standing or walking
An unstable foot due to the heel tilting inward, which can lead to ankle sprains
Some people with cavus foot may also experience foot drop, a weakness of the muscles in the foot and ankle that results in dragging the foot when taking a step.
If a foot drop is present this is usually due to an underlying neurologic condition.
