Treat the tops and soles of your feet as two separate, directly exposed surfaces. You can include both in one routine if your device can be safely repositioned between them, but do not assume that light reaching the top of the foot also reaches the sole. Keep bare feet in a clear line of sight to the light source, follow your model's approved orientation, distance, and session settings, then reposition for the second surface.
Use Two Positions for Complete Foot Coverage
The simplest approach is to divide your foot routine into two passes:
- Expose the tops of both feet with the dorsal surfaces facing the device.
- Reposition for the soles so the plantar surfaces face the device directly.
This can happen in one sitting, provided the device remains in an approved, stable position and you can change your foot position without obstructing the light or compromising comfort.
A horizontal-facing panel or lamp can work well for the tops of the feet when you are seated with both feet pointed toward the emitting surface. For the soles, sit so you can lift, extend, or angle your feet until the bottoms face the device. If your device is approved for a downward- or upward-facing setup, that orientation may also make one of the two passes easier---but only use configurations permitted in its instructions.
The key is not the direction of the device alone. It is whether the intended foot surface has a direct, unobstructed view of the light.
Position for the Tops of Your Feet
For dorsal exposure, sit or stand at the distance specified for your device and point the tops of both feet toward the light source.
Before starting, check that:
- Shoes and socks are removed.
- Toes are relaxed rather than curled under.
- Both feet are within the intended treatment area.
- A chair, device stand, furniture edge, or the opposite foot is not blocking part of either foot.
- The ankles are positioned so the top of each foot, rather than mostly the shin, faces the light.
A slightly spread foot stance can help prevent one foot from shading the other. If your toes are angled sharply upward or downward, their position may also create small shadowed areas near the toes or along the top of the foot. A comfortable, neutral placement is usually easier to repeat from session to session.
Reposition for the Soles Instead of Relying on Spill Light
The soles need their own direct exposure. After completing the top-of-foot position, turn or lift your feet so the bottoms face the emitting surface.
For a panel positioned in front of you, sit back far enough to place your soles toward the panel without resting them against it or creating an unstable posture. You might extend your legs slightly, elevate your feet, or lean back in a chair, depending on the approved device setup and what is comfortable.
Check the following before beginning the sole pass:
- The arches and heels face the light rather than being hidden by the chair edge or floor.
- Toes are not folded tightly enough to block the forefoot.
- One sole is not positioned behind the other.
- The device stand, frame, or mounting hardware does not cast a shadow across the feet.
- You can maintain the position without strain or slipping.
If you cannot comfortably expose both soles at once, treat one sole at a time or split the top and sole positions into separate routines. A repeatable setup is more useful than forcing an awkward position.
Do Not Use Sole Thickness to Change Your Settings
The skin on the sole differs from the skin on the top of the foot, but that does not create a universal instruction to move closer, increase power, or extend the session. A review of photobiomodulation protocols describes red light and near-infrared light as distinct ranges used in photobiomodulation, but it does not establish a foot-specific setting choice.
Use the distance, timing, mode, cooling requirements, and placement limits supplied for your exact device. Do not transfer settings from another device type, body area, or online routine.
Prepare Your Feet and Check for Shadows
Start with bare, clean, dry feet. Remove footwear and socks so they do not block the intended treatment area. Unless your device instructions specifically address them, do not assume that lotion, sunscreen, or other topical products are appropriate during a session.
Once the light is on, use the visible beam or illuminated area as a practical coverage check. Look for missed zones around:
- The sides of the feet
- The heel edges
- The arch
- The spaces between toes
- The area beneath curled toes
- Any spot blocked by furniture, a stand, or the opposite foot
Avoid trying to solve a shadow by moving closer than instructed. Instead, adjust the foot angle, separate the feet, or reposition for another direct pass.
Follow Your Device's Setup and Eye-Safety Directions
Photobiomodulation devices may use different light sources, including LEDs and low-level lasers, and their coverage, controls, mounting options, and operating instructions are not interchangeable. Follow the instructions for your specific device rather than treating a panel, lamp, pad, or other device as though it has identical placement rules.
For a BestQool device, check the instructions supplied with your model for approved orientation, operating distance, session controls, ventilation requirements, and eye-safety directions. Keep the device stable, do not block its cooling or ventilation features, and use any recommended eyewear or viewing precautions.
Stop the routine if the setup becomes uncomfortably warm or if your skin response concerns you.
Two-Surface Foot Setup Checklist
- Expose the tops of your feet directly rather than relying on light reaching them at an angle.
- Reposition your feet or the approved device setup to expose the soles directly.
- Keep feet bare and free of shadows from toes, arches, stands, furniture, or the opposite foot.
- Use only the distance, timing, orientation, and session controls specified for your device.
- Do not increase exposure simply because the sole skin is thicker.
- Pause for clinical guidance before self-treating if you have reduced foot sensation, neuropathy, poor circulation, open wounds, diabetes-related foot concerns, unusual skin changes, photosensitivity risks, or photosensitizing medicines.
- For model-specific placement and safety directions, use the manual or support materials provided with your BestQool device.
