Understanding Flexible Flat Feet & Arch Support

How Arch Collapse Affects Your Body

When you stand on a flexible flat foot, the medial arch flattens toward the ground. Looking at the rear of the foot, the heel bone shifts from a vertical position and tilts inward. This movement, known as overpronation, alters how force travels up the leg, placing extra mechanical stress on the inner ankle, knee joint, hips, and lower back.

How Orthotic Insoles Help Support Your Feet

Podiatrists help manage flexible flat feet by supporting the arch with structured orthotic insoles. Whether custom-moulded or quality off-the-shelf options, orthotic insoles hold the arch at a natural height and resist excess inward rolling. By keeping the heel bone in a more neutral alignment, orthotics help reduce strain across the lower limbs so you can walk further with greater comfort.

Signs and Characteristics of Flexible Flat Feet

• An arch is visible when sitting, but collapses when standing.
• The heel bone tilts inward under body weight (overpronation).
• Can contribute to aching arches, knee tiredness, or lower back strain.
• Supportive orthotic insoles help limit excess arch collapse during activity.
