Flat Feet Exercise Program: A Research-Based Solution
Key insights: 60-second read
- 6-week exercise program significantly improves foot alignment – A 2022 RCT found comprehensive exercises reduced navicular drop by 0.4cm and improved arch angle by 16° in flexible flat feet.
- Program combines short foot, gluteal, and ankle exercises – Progressive overload from sitting to standing to single-leg stance over 6 weeks.
- Excellent compliance and safety – 96% completion rate with no adverse events reported.
- Addresses both local and proximal contributors – Targets intrinsic foot muscles and hip stabilisers for comprehensive flat foot management.
As a Physiotherapist, I'm always seeking evidence-based approaches to help patients with common musculoskeletal issues like flat feet. Interesting research published in the Journal of Physiotherapy reveals that a specific exercise program can significantly improve foot alignment in people with flexible flat feet. This randomised controlled trial provides compelling evidence that could better inform how we approach flat foot management in clinical practice. (1)
Key Research Finding
A comprehensive 6-week exercise program reduced navicular drop height by 0.4cm more than basic exercises alone and improved medial longitudinal arch angle by 16 degrees in people with flexible flat feet. These improvements were statistically significant (95% CI 0.4 to 0.5 for navicular drop; 95% CI 13 to 19 for arch angle) and clinically meaningful for foot alignment.

1. Study Overview and Methodology
The study followed 52 participants with flexible flat feet in a randomised controlled trial with concealed allocation and blinded assessors. Participants were allocated to either an experimental group performing comprehensive exercises or a control group performing basic ankle movements for 6 weeks. (1)
Participant Characteristics
| Characteristic | Experimental Group | Control Group |
|---|---|---|
| Average Age | 21.1 years | 20.5 years |
| Body Mass Index | 23.0 kg/m² | 23.5 kg/m² |
| Baseline Navicular Drop | 1.5 cm | 1.6 cm |
| Baseline Arch Angle | 120° | 115° |
Research Methods
The study employed rigorous methodology to ensure reliable results:
- Randomised Design: Participants were randomly assigned to experimental or control groups using concealed allocation
- Blinded Assessment: Outcome assessors were unaware of group assignments to prevent measurement bias
- Objective Measures: Navicular drop height and medial longitudinal arch angle were measured using standardised protocols
- Intention-to-Treat Analysis: All randomised participants were included in the final analysis, maintaining group comparability
2. Key Research Findings
The study yielded several important findings with significant clinical implications:
Structural Improvements in Foot Alignment
The comprehensive exercise program produced substantially greater improvements in both primary outcome measures compared to basic exercises. The 0.4cm reduction in navicular drop represents meaningful clinical progress, as navicular drop >1cm is diagnostic of flat feet.
Progressive Benefits Over Time
Improvements were achieved through a progressively challenging program that advanced from sitting to standing to single-leg stance positions over the 6-week period. This progressive overload principle appears crucial for strengthening the dynamic stabilizers of the foot arch.
Excellent Compliance and Safety
The program demonstrated excellent adherence with only one dropout in the experimental group (96% completion rate) and no reported adverse events. This suggests the exercises are both safe and practical for most people with flexible flat feet.
3. The Evidence-Based Exercise Program
Here's the exact program that produced these significant results, performed three times per week for 6 weeks:
Core Exercise Components
| Exercise Type | Specific Exercises | Progression |
|---|---|---|
| Short Foot Exercises | Toe spread, hallux extension, doming, lesser toe extension | Weeks 1-2: Sitting Weeks 3-4: Standing Weeks 5-6: Single-leg stance |
| Gluteal Strengthening | Hip abduction, hip extension | Increase hold time from 0 to 10 seconds over 6 weeks |
| Ankle Movements | Dorsiflexion, plantarflexion | Consistent throughout program |
| Stretching | Calf stretches | Consistent throughout program |
4. Why This Program Works
- Targets Intrinsic Foot Muscles: Short foot exercises specifically activate abductor hallucis, flexor digitorum brevis, and quadratus plantae - key dynamic stabilisers of the medial longitudinal arch
- Addresses Kinetic Chain: Gluteal strengthening helps control hip internal rotation, reducing compensatory foot pronation
- Progressive Overload: Systematic progression challenges the foot stabilisers as they strengthen
5. Study Limitations and Generalisability
Population Specificity
The study focused on young adults (18-21 years), which may limit direct application to older populations or those with different activity levels. Additionally, the sample size, while sufficient for precise estimates, was relatively small.
Measurement Considerations
Outcomes were biomechanical rather than patient-reported measures like pain or function. While structural improvements are important, their relationship to symptom reduction requires further investigation.
Long-Term Effects Unknown
The study assessed outcomes immediately after the 6-week intervention without follow-up to determine if improvements were maintained long-term. Ongoing exercise may be necessary to sustain benefits.
Conclusion and Clinical Takeaways
This research provides strong evidence that a comprehensive, progressive exercise program can significantly improve arch position in people with flexible flat feet. The 6-week program combining short foot exercises, glute strengthening, and stretching resulted in meaningful improvements in both navicular drop height and medial longitudinal arch angle.
The consistent benefits across participants suggest that addressing both local foot muscles and proximal hip stabilisers creates an optimal approach for flat foot management. By incorporating these evidence-based exercises into your self-treatment plan, we can utilise an active approach that goes beyond passive supports and may produce lasting structural improvements.

Frequently Asked Questions
Can exercises really fix flat feet?
Yes, a 2022 RCT found that a comprehensive 6-week exercise program significantly improved foot alignment in people with flexible flat feet. Participants achieved a 0.4cm reduction in navicular drop and a 16° improvement in arch angle. The program combined short foot exercises, glute strengthening, and stretching with progressive overload.
What exercises are best for flat feet?
The research-backed program includes: short foot exercises (toe spread, doming), gluteal strengthening (hip abduction, extension), ankle movements, and calf stretches. The key is progressive overload - advancing from sitting to standing to single-leg stance over 6 weeks.
How long does it take to improve flat feet with exercise?
The study showed significant improvements after 6 weeks of training three times per week. However, long-term maintenance is unknown - ongoing exercise may be needed to sustain benefits. The program had excellent compliance with 96% completion rate.
What are the limitations of this flat feet research?
The study focused on young adults (18-21 years), so results may not generalise to older populations. Outcomes were biomechanical rather than patient-reported (pain/function), and long-term follow-up wasn't performed to assess whether improvements were maintained.
One profound insight from this post
"A 6-week comprehensive exercise program combining short foot exercises, glute strengthening, and stretching reduced navicular drop by 0.4cm and improved arch angle by 16° - meaningful clinical progress for flexible flat feet."
