Increased Femoral Anteversion is a transverse plan problem that affects lower body alignment, walking and standing characteristics and also pes planovalgus mostly accompanies with IFA. It is shown that children with IFA and PPV have back and leg pain, fatigue, muscle cramps and they are under the risk for chronic disorders such as osteoarthritis, scoliosis and muscle injuries.

Insoles, which reduce pronation of foot (flat foot), provide apparently a static correction by supporting proper alignment in children with IFA and PPV. However, the dynamic effects of insoles to lower extremity biomechanics while walking is not known.

The aims of this study are to determine the effects of the insoles on walking biomechanics in children with IFA and PPV by comparing with their healthy peers.

Inclusion Criteria:

• Insole Group Between the ages 7-15, Trochanteric Prominens Angle Test > 20⁰, Hip internal rotation angle > 60⁰, Without insole Foot Posture Index score > 5, With insole Foot Posture Index score > 4, Using their insoles' at least one month.
• Control Group Between the ages 7-15, Trochanteric Prominens Angle Test < 20⁰, Foot Posture Index score < 5, Without any neurologic or orthopedic disease

Exclusion Criteria:

Neurological and / or musculoskeletal problems, Orthopedic problems to prevent walking.
