In-shoe Pressure Analysis (F-Scan)

• Sensor fitting — a thin sensor is placed inside your shoe, calibrated to your body weight and gait.
• Walking and/or running assessment — you move naturally on a treadmill (or, where appropriate, outdoors) while the system records pressure data in real time.
• Three testing scenarios — every In-shoe Pressure Analysis appointment includes three separate testing conditions (for example, different footwear, with and without an orthotic, or walking versus running), so we’re comparing like-for-like rather than relying on a single pass.
• Live review — you see your own pressure map on screen, colour-coded to show high- and low-pressure areas, while your clinician explains what it means in plain language.
• Written summary — a plain-English report is provided after your appointment, with the clinical detail available on request for your GP, consultant, or referring clinician.

3D Gait Analysis and In-shoe Pressure Analysis answer two different but connected questions:

• 3D Gait Analysis (Run3D) captures your movement — joint angles, symmetry, timing, and how your whole body moves as you walk or run.
• In-shoe Pressure Analysis (F-Scan) captures the consequence of that movement — exactly where and how much load goes through your foot as a result.

Used together, they give a complete picture: we can see a movement pattern on Run3D, then confirm on In-shoe Pressure Analysis whether that pattern is actually causing excess load somewhere specific for example, through the forefoot, the outside of the heel, or unevenly between left and right.

For patients who’ve already had a 3D Gait Analysis with us, adding In-shoe Pressure Analysis builds directly on that assessment rather than duplicating it. We offer a combined package for exactly this reason.

One of the most valuable uses of In-shoe Pressure Analysis is proving whether a custom orthotic is doing its job. At NK Active, we design and 3D print custom orthotics in-house. In-shoe Pressure Analysis lets us:

• Verify that a newly fitted orthotic is redistributing pressure the way it was designed to.
• Compare pressure maps with and without the orthotic in place, side by side.
• Adjust the design with objective evidence if the intended redistribution isn’t showing up.
• Review orthotics at follow-up appointments to confirm they’re still performing as expected over time.

Instead of relying on how an orthotic feels, you get to see, on screen, exactly what it’s doing.

Footwear changes how load moves through your foot, sometimes significantly. In-shoe Pressure Analysis lets us test the same foot, the same movement, across different pairs of shoes — useful if you’re:

• Choosing between running shoe models and want objective data, not just a guess based on feel.
• Investigating whether a specific pair of shoes is contributing to recurring pain (forefoot, heel, or arch-related).
• Assessing work or sports footwear for pressure-related risk, including diabetic-safe footwear checks.

• Wear custom orthotics and want proof they’re working
• Have recurring forefoot pain or metatarsalgia
• Are managing diabetic foot risk and need an offloading assessment
• Are a runner dealing with load-related injuries
• Want to compare footwear options objectively
• Have had a 3D Gait Analysis and want to understand the loading side of your movement pattern
