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.
Full 3D GRF & Kinematics Data
Side-to-Side Forces
Critical for assessing balance, asymmetry, and injury risk
Vertical Forces
Essential for impact and load studies
Forward, Backward Forces
Key for assessing 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.
