Flatfoot is often a complex disorder, with diverse symptoms and varying degrees of deformity and disability. There are several types of flatfoot, all of which have one characteristic in common: partial or total collapse (loss) of the arch.
Other characteristics shared by most types of flatfoot include:
- “Toe drift,” in which the toes and front part of the foot point outward
- The heel tilts toward the outside and the ankle appears to turn in
- A tight Achilles tendon, which causes the heel to lift off the ground earlier when walking and may make the problem worse
- Bunions and hammertoes may develop as a result of a flatfoot.
