What is adult acquired flatfoot?

Adult acquired flatfoot (PTTD) develops when the posterior tibial tendon weakens and the arch collapses over time. The foot rolls inward, the heel drifts outward, and the arch disappears — causing pain and instability.

How ArchAnchor™ helps

ArchAnchor™ provides firm medial arch support and rearfoot varus posting to realign the foot, reducing stress on the posterior tibial tendon and preventing progressive arch collapse.

What causes PTTD?

Chronic overuse, obesity, and flat-footed gait strain the posterior tibial tendon, leading to progressive tendon degeneration and arch collapse.

Can an orthotic stop the collapse?

Orthotics are the first-line conservative intervention for Stage I and II PTTD — they reduce tendon load and slow or halt arch deterioration.

Do I need a rigid or flexible orthotic?

A semi-rigid device with a firm medial arch and varus rearfoot post is typically recommended to provide both support and some dynamic function.
