What is 3D foot scanner used for?

The scanner uses cameras or light to create a digital model of the foot. Depending on the system, the clinician may compare the two feet, examine arch shape, and observe how the foot contacts the ground. A scan is a measurement tool, not a diagnosis on its own. Symptoms, strength, joint movement, footwear, and walking pattern still matter when interpreting the result. A clinician may use the information when considering [Custom Orthotics](/treatments/non-surgical-orthopedics/custom-orthotics/).

You may be asked to stand still, walk, or place each foot on a scanning platform. Wear comfortable clothing and bring the shoes you use most, particularly if the scan is related to walking or sport. Tell the clinician about pain, numbness, previous injuries, diabetes, skin problems, and the activities you want to resume. The result may guide footwear advice, exercises, load changes, or an orthotic design. It should be combined with an examination and reviewed if your symptoms change.

Seek prompt care for a foot that is suddenly cold, pale, severely swollen, or unable to bear weight after an injury. Urgent assessment is also appropriate for a spreading wound, fever with foot redness, new severe numbness, or rapidly worsening weakness. A scanner is not a substitute for urgent examination when circulation, infection, or a serious injury may be involved.

Ask: What does this scan measure in my case? How does it fit with the physical examination? Would footwear or exercises be tried before an orthotic? When should the scan or fitting be reviewed?
