For years we have been dedicated to a single mission: to unchain Ground Reaction Force analysis from the traditional lab. The XO-SOLE was the result of that dedication—a validated, high-fidelity in-shoe sensor system designed for the rigorous demands of researchers, biomechanists, and clinicians. The XO-SOLE allows you to move beyond the limitations of force plates and capture accurate, reliable GRF data in the field, on the track, or in the clinic. We now introduce the XO-SOLE Rev 5, offering upgrades in performance, connectivity, and comfort.

Key Features & Benefits

• Extended Battery Life: An increase from 12 hours to 20 hours of battery life.
• Increased Bluetooth Connectivity: Increased wireless connectivity through the app to ensure your data is captured at greater distances and more accurately.
• Slimmer, Lighter Design: The newest update offers a thinner, slimmer design to increase comfort while still offering the same durability.
• Lab-Validated Accuracy: A comprehensive laboratory study with over 65 participants confirms the XO-SOLE's exceptional accuracy for GRF measurement. Trust your data.
• Collect Data in Any Environment: The untethered, in-shoe design liberates your research. Analyze gait, running, and athletic movements in their natural context.
• Full Access to Raw Data: We believe your data is yours. Export raw sensor data directly from the XO-SOLE for complete control and analysis in your preferred software (MATLAB, Python, R, etc.).
• Designed for Researchers: With features like multi-unit synchronization, long-life battery for extended data collection, and a robust software suite, the XO-SOLE is built for the workflow of a modern research lab.
• Durable & Reliable Construction: Built to withstand the demands of repeated trials and high-impact activities, ensuring a long and productive life for your investment.
