Arch or heel fatigue
Standing, walking, or exercise may lead to aching through the arch, heel, or inside of the ankle.

Flat feet & arch pain
A low arch is not automatically a problem. Evaluation becomes important when flat feet are painful, increasingly one-sided, stiff, swollen, or limiting walking and activity.
Symptoms and changes
The arch may lower only while standing or remain flat when seated. Symptoms, flexibility, tendon function, and whether one or both feet are affected help guide the evaluation.
Standing, walking, or exercise may lead to aching through the arch, heel, or inside of the ankle.
The heel may tilt and the ankle may appear to roll inward while weight bearing.
Uneven wear, widening of the foot, or pressure against footwear may become noticeable.
A newly changing arch—especially with swelling or inner ankle pain—deserves a focused assessment.
A cause-specific assessment
The examination may compare both feet while sitting and standing, review walking mechanics, test flexibility and strength, and assess the posterior tibial tendon, Achilles tendon, joints, and areas of tenderness. Imaging may be considered when appropriate.
Determine whether the arch returns without weight and how much motion remains in the foot and ankle.
Separate tendon, joint, plantar fascia, bone, and nerve-related patterns that can overlap.
Build a plan around symptoms, activity needs, footwear, foot shape, and progression over time.
Support without overpromising
Painless flexible flat feet often do not require treatment. The goal is not to create a “perfect” arch—it is to address pain, instability, progression, and limits on daily activity.
When evaluation should not wait
Arrange timely evaluation for persistent pain, increasing swelling, a rapidly changing or one-sided arch, difficulty standing on the toes, new numbness, an open sore, or reduced ability to walk. Seek urgent care for a cold or discolored foot, severe injury, or sudden inability to bear weight.
A newly fallen arch in an adult can involve the arch-supporting posterior tibial tendon and should not be assumed to be only a shoe problem.
