Understanding Your Foot: Flat Feet, Normal Arches & High Arches
Your feet are the foundation of your body, absorbing shock, supporting weight, and maintaining balance with every step. Variations in the foot arch — flat, normal, or high — influence not only foot comfort but also knee, hip, and back health.
At Form & Function in Markham, we use a Footmaxx digital pressure mat assessment to analyze foot structure, pressure distribution, and gait patterns. This initial assessment is ideal for those who are unsure of their arch type and helps guide whether a full custom orthotic fitting with a 3D laser scan is needed.
What Is the Arch of the Foot?
The arch is the curved structure along the sole of the foot, particularly the medial longitudinal arch, running from heel to ball of the foot. It acts as a shock absorber, distributes weight, and supports the body during standing, walking, or running.
Variations in arch height or function can contribute to foot pain, altered biomechanics, and discomfort in the knees, hips, or back. A Footmaxx digital pressure mat assessment identifies your arch type and highlights pressure points, while a 3D laser scan allows a full custom orthotic fitting for optimal support.
1. Flat Feet (Low or Collapsed Arch)
Definition & Key Features
A flat foot occurs when the medial arch is low or collapses under weight, often resulting in over-pronation.
Why Digital Pressure Assessment Matters
The Footmaxx digital pressure mat detects subtle arch collapse and uneven force distribution, helping determine if a custom orthotic is needed.
Biomechanical Implications & Clinical Signs
- Reduced shock absorption and uneven force distribution.
- Heel tilts outward (valgus), inward knee movement, increased foot contact area.
- Tired feet, heel/ankle pain, knee or hip discomfort.
Clinic Approach
- Initial assessment: Digital pressure mat to confirm arch type.
- Full custom fitting (if needed): 3D laser scan for precise orthotic creation.
- Orthotics: Footmaxx inserts with arch support and medial flange if needed.
- Stability footwear, foot strengthening, hip/core exercises.
- Follow-up to adjust orthotics over time.
2. Normal Foot Arch
Definition & Key Features
Neutral arches maintain balance under load, with slight mid-stance pronation returning to neutral.
Role of Digital Pressure Assessment
The Footmaxx pressure mat can reveal subtle imbalances or early signs of overuse, guiding whether custom orthotics in Markham may be beneficial.
Management & Maintenance
- Proper footwear and awareness of foot loading.
- Orthotics can optimize function, especially during high-impact activities.
- Periodic reassessment for changes in activity, weight, or injury.
3. High Arch (Cavus Foot)
Definition & Key Features
High arches are elevated and rigid, often leading to under-pronation (supination) and lateral loading.
Importance of Assessment
- Digital pressure mat: Reveals high-pressure areas and lateral loading.
- 3D laser scan: Allows a fully customized orthotic to provide cushioning, arch support, and pressure redistribution.
Management & Treatment
- Foot mobility assessment: calf tightness, plantar fascia, peroneal overuse.
- Custom orthotics with appropriate arch support and shock absorption.
- Flexible, cushioned footwear; training for foot, ankle, hip, and core stability.
Why Foot Mechanics Matter Beyond the Foot
Foot alignment impacts the entire kinetic chain:
- Flat feet → inward tibial rotation → knee/hip compensation → low back strain.
- High arches → reduced shock absorption → higher impact on knees, hips, and spine.
A combination of digital pressure assessment, 3D laser scanning, and custom orthotics in Markham ensures precise correction and reduces foot pain while improving overall movement mechanics.
Patient-Centered Approach at Form & Function
- Initial Digital Pressure Assessment: Quick, non-invasive test with clinical support staff for those unsure of their arch type.
- 3D Laser Scan for Custom Orthotics: Detailed scan to create fully personalized Footmaxx orthotics.
- Footwear & Education: Optimize orthotic use with proper shoes and guidance.
- Strength, Mobility & Stability Training: Foot intrinsics, ankle mobility, and hip/core integration.
- Ongoing Monitoring & Adjustment: Orthotics adjusted over time for changes in activity, weight, or aging.
Final Thoughts
Flat feet, normal arches, and high arches each have unique biomechanical characteristics. Determining your arch type with a Footmaxx digital pressure mat assessment is the first step. If needed, a 3D laser scan enables a full custom orthotic fitting for optimal comfort and function.
With proper footwear, targeted strength training, and custom orthotics in Markham, patients can significantly reduce foot pain and improve overall biomechanics.
