Insole Scanning

This will guide you through the process of scanning for a custom insole. In this example we will scan the foot in an unloaded state with an aligned, straight heel bone, straight Achilles tendon and activated arch. For the neutral foot position, the foot is pre-tensioned using the Windlass technique, which simulates the dynamics of the foot when walking. This is best done with a second person scanning the client.

1. Position the Customer

For the scanning process, the customer crosses one leg over the other, with the lower leg of the leg to be scanned touching the thigh of the second leg just above the ankle. Ideally, the second leg should be bent at a 90° angle.

2. Arm Position

The arm on the same side as the foot to be scanned is placed with the elbow on the tibial head of the foot to be scanned and the customer grasps the toes of the foot with the same hand. This assumes the basic scanning position and the scan for the first foot can be carried out.

3. Alignment

The alignment of the calcaneus and Achilles tendon is important when adjusting the scan position; both components of the foot must be aligned with each other and the foot must not have any twisting in the forefoot.

For correct tension of the plantar fascia, the wrapped toes are pulled slightly towards the shin with the hand. As a rule, gripping the first and/or second toe is sufficient to achieve sufficient pretension. When building up tension in the plantar fascia, it is essential to ensure that too much tension is not built up here.

4. Scanning

Structure scanning hardware works best in soft lighting conditions, incandescent light or shaded light will work the best. If you see artifacts in the scan, you can wear a brightly colored sock in green or yellow during the scan process. Adjust the wireframe bounding box so the foot is contained inside the box. Slowly move the iPad around the foot until fully captured.
