Study-Validated Accuracy For Biomechanics Research

3D GRF Measuring

XO-SOLE PRO has been scientifically validated against force-instrumented treadmills, the gold standard for GRF measurement. The XO-SOLE PRO shows excellent reliability across mediolateral, anteroposterior, and vertical forces, while most wearable technologies are limited solely to vertical.

Mediolateral (side to side)

Critical for assessing balance, asymmetry, and injury risk

Vertical GRF graph.

Essential for impact and loading studies

Anteroposterior GRF graph.

Anteroposterior (forward and back)

Key for propulsion and braking efficiency

GRF 101. GRF (ground reaction force) is the force the ground pushes back with every time your body makes contact, whether you’re walking, running, or jumping. These forces move in three directions: side to side (mediolateral), up and down (vertical), and forward and backward (anteroposterior). By measuring GRF, you can better understand who someone moves, and even assess their balance, movement efficiency, and potential risk of injury. XO-SOLE PRO captures all these forces for you in a small, portable, self-contained system. It’s basically like having a lab in your shoe.
