Anatomy & Body Systems
Overview of Affected Body Systems
1. Skeletal System
The foot contains 26 bones forming three structural arches:
- Medial Longitudinal Arch : The primary arch, most affected in high arches
- Lateral Longitudinal Arch : Along the outer edge
- Transverse Arch : Across the width of the foot
In high arches, these structures are elevated, reducing ground contact in the midfoot and concentrating forces on the heel and ball of the foot.
2. Muscular System
Intrinsic Muscles:
- Plantar Muscles : Support arch; often weak in high arches
- Dorsal Muscles : May become overactive
Extrinsic Muscles:
- Posterior Leg Muscles (Gastrocnemius, Soleus) : Often tight in high arches
- Anterior Tibial Muscle : May be overactive
- Peroneal Muscles : Lateral stabilizers; may be weak
3. Ligamentous Support
- Plantar Fascia : Thick connective tissue; critical for arch support
- Spring Ligament : Supports navicular
- Long/Short Plantar Ligaments : Support lateral arch
4. Biomechanical Impact
High arches create a "rigid lever" rather than the "flexible adaptor" that normal arches provide:
- Reduced shock absorption
- Increased lateral stress on ankle
- Higher pressure under heel and ball of foot
- Compensatory changes up the kinetic chain
We assess high arches as part of the entire kinetic chain, recognizing how foot structure affects ankle, knee, hip, and spine mechanics.

FAQ
Q: Are high arches a problem? A: Not necessarily. Many people with high arches have no symptoms. However, high arches can cause pain, instability, and difficulty finding shoes. Evaluation is recommended if symptoms occur.
Q: Can high arches be corrected? A: Mild to moderate flexible high arches may be managed conservatively with orthotics and exercises. Rigid deformities and severe cases may require surgical intervention. The goal is typically symptom management rather than complete correction.
Q: What causes high arches? A: High arches can be hereditary or associated with neurological conditions like Charcot-Marie-Tooth disease. Most cases are congenital/idiopathic.
Q: Do high arches need special shoes? A: Yes, high arches often require shoes with good cushioning and support. Avoiding completely flat shoes is recommended. Orthotics can help redistribute pressure.
Q: Can high arches cause knee pain? A: Yes. High arches alter lower limb mechanics, which can contribute to knee pain. The rigid, supinated foot doesn't absorb shock well, transmitting increased stress to the knee.
