Gait & Motion Insoles

The X4 Intelligent Insole is a plantar pressure and gait measurement system for athletic coaches and clinicians to capture lab-quality data in the field.

It can be challenging to measure plantar pressure and analyze gait accurately, consistently, and in the environments where activity normally takes place: outside of the lab. In the past, capturing natural gait has been limited because current products are not suited for real-world testing.

X4 Intelligent Insole System

Evaluate gait, plantar pressure, and foot function with insole sensors that are reliable and durable enough to accurately capture data wherever activity takes place — and without compromising natural motion. Avoid set-up and recalibration issues that can be costly and impact the accuracy of your data.



Get out of the lab. Optimize athletic performance.

Gain precise insights into athletic activity with insoles that are built for collecting lab-quality data in the field. Use wireless, undetectable sensors to collect plantar pressure data to inform intervention strategies and reduce the risk of athletic injuries.



Provide the best orthotics with real-time feedback.

Use plantar pressure data to design orthotics that perfectly fit your patients to save time and avoid injury. Understand the impact of surgical or therapeutic interventions with real-time feedback to support treatment plans for patients who suffer from foot pain or are at risk for diabetic foot ulcers.



Designed with robust sensors and electronics.

The sensors are durable and reliable, making them ideal for continuous use in research or sports performance testing. The easy-to-use sensors are ready out of the box and support trouble-free testing. Lab time is valuable and with the X4 system, users can keep set-up time to minutes.



Feature-rich software
and highly detailed visualizations.

XSENSOR’s Pro Foot & Gait software provides high-resolution images for fast, confident decision making and our Pro version has all the necessary features and tools for clinicians interested in more detailed analysis of patient’s progress. With the easy-to-use file manager, users can display and compare multiple recordings side-by-side, complete with summary statistics and measurements, and generate reports.
