Our feet do not always behave like mirror images. Differences between the left and right orthotics may be intentional, but they should be explained in terms of the assessment rather than treated as proof that one foot is defective.
Different does not automatically mean abnormal
Previous injury, mobility, foot shape, habitual loading and the task being measured can all contribute to differences. Some variation is normal. A single scan cannot establish why every difference exists or whether it needs treatment. Your clinician considers symptoms and examination findings before deciding whether an asymmetry is relevant. The goal is not to force every pair of footprints to look identical on a screen.
Prescriptions can reflect different needs
One side may need a different accommodation or support strategy if the assessment supports it. The two devices might also feel different during fitting. Ask the clinician to identify the left and right and explain the intended purpose of any obvious difference. Do not swap them to make the pressure feel more equal. Do not copy a friend’s prescription because their feet appear similar. External appearance alone does not establish the same clinical need.
Do not infer a leg-length correction
An uneven pressure pattern does not automatically mean you need a heel lift or that one leg is shorter. Suspected leg-length difference requires appropriate assessment, and adding a lift yourself can change shoe fit and loading. If one side becomes painful or the shoe feels unstable, bring both devices and both shoes back for review. An understandable, comfortable plan matters more than cosmetic symmetry between the printed shapes.
Where Footscan and PHITS fit at P.O.R.C
P.O.R.C — Prosthetic & Orthotic Rehabilitation Clinic — has been serving since 1988. For people exploring custom insoles in Delhi, the clinic uses Footscan and PHITS 3D-printed insoles as part of an individual assessment pathway. A scan is not a diagnosis. It can add loading information to the clinical picture, but it does not by itself establish that you need an orthotic or predict the result.
If you are considering 3D printed orthotics in South Delhi or elsewhere in Delhi NCR, start with the problem you want help with rather than requesting a particular contour. Your symptoms, medical history, examination, footwear and activities help determine the next step. The team may discuss a prescribed device, simpler support, footwear changes, rehabilitation or a medical referral. Outcomes vary, and no insole should be presented as a guaranteed cure.
Read about Footscan and custom insoles before your visit. For local access, see Safdarjung Enclave. P.O.R.C also has branch information for Safdarjung Enclave, Apollo Sarita Vihar and BLK-Max. Confirm the appointment location and service arrangements with the clinic; a branch page is not a promise of walk-in availability.
A useful next step
Before a consultation, write down the one activity you most want to do more comfortably and the question this guide raises for you. Ask the clinician to relate any proposed prescription to that goal. Keep a note of agreed instructions so you can describe your experience accurately at follow-up. Do not adjust the device yourself if the plan is unclear; contact the treating team for advice.
Short FAQ
Should the left and right prescriptions always match?
No. They may differ when assessment supports different needs, but those differences should be explained.
Can a Footscan explain every cause of foot pain?
No. Pressure information is one part of an assessment. Some symptoms need medical examination or other investigations before an orthotic is considered.
What should I bring to a review?
Bring the shoes and socks you actually use, your current inserts if any, relevant reports and a short account of your symptoms. Ask about the intended goal, alternatives, care instructions and follow-up before committing to a device.
