Flat valgus foot

The term flat valgus foot is a collective term for a group of creature-like foot malpositions, which are characterized by an abductive pronation position of the foot. This malposition is characterized by a reduction, cancellation or reversal of the longitudinal arch of the foot and a lateral deviation of the forefoot and hindfoot.

There are numerous forms between slight deformations and extreme deformations of stiffened flat feet. If the longitudinal arch (flatfoot) lowers and the foot bends outwards at the same time, whereby the heel rotates inwards (pes valgus), it is considered to be flat valgus foot. This foot deformity can transition easily into flatfoot.  


Talus verticalis (also known congenital flatfoot) represents the most pronounced, contracted flatfoot deformity. It is often seen in children suffering from AMC, for example. This foot deformity is usually treated surgically. After that, an orthotic treatment can be considered.

Flat valgus foot often occurs in children with a misalignment of the leg axis (e.g. X-legs). This foot deformity can lead to knee problems due to incorrect loading. Depending on the stage of the disease, a decision must be made as to whether a pediatric flat valgus foot is to be treated surgically or conservatively. Flexible flat valgus feet without structural Achilles tendon shortening (i.e. without foot drop) can be treated conservatively with a talus repositioning ring orthosis (TRRO).

Orthoses for foot, leg and hip

An orthosis is used to stabilize, relieve, immobilize, guide or correct limbs. This prevents or corrects incorrect postures and strains.

Shoes for orthoses wearers

When choosing orthotic shoes, it is important for the combination of orthotic and shoe to be right for the purpose and for the desired effect of the treatment to be achieved. There are numerous models with different designs.
