Pace is the result. Gait is how you produced it.
Gait analysis connects timing, movement, and ground interaction. Cadence and contact time describe when a step happens. Motion describes how the foot moves. Pressure and force describe how the runner meets the ground. Variability and left–right comparisons reveal whether that strategy repeats.1,2
Put together, those measurements describe the mechanics alongside the pace: not only that the runner sped up or slowed down, but what changed under each foot as it happened.
Every step is a connected sequence
Landing shows where and how load arrives. Midstance shows how the foot adapts and carries the body forward. Push-off shows where pressure finishes and how quickly the foot leaves. The next contact reveals whether the opposite side repeats the same strategy.
A single average erases that sequence. STRIV keeps the phases connected so cadence, contact time, pressure distribution, CoP, pronation-related motion, and force can be read as one step—not six unrelated charts.
The signal at the foot opens a window on the whole chain
Researchers have used plantar-pressure signals to reconstruct continuous running ground-reaction forces, and instrumented-insoles to estimate knee contact force and knee moments across walking, running, and daily movements.5,6
Wearable motion models have also estimated structure-specific peaks, impulses, and loading rates around the Achilles tendon, patellar tendon, ankle, and knee during running. These advances are why the foot–ground signal matters: it is the mechanical starting point for understanding how load travels through the runner.7
STRIV turns that starting point into something runners can collect every session—not only during an occasional lab visit.
26 measurements. Two feet. One running story.
With 128 pressure sensors beneath each foot plus motion sensing, STRIV captures 26 measurements per step. That includes pressure distribution, CoP progression, timing, pronation-related roll, peak vertical GRF, loading rate, cadence, and left–right differences.
The value is not the metric count. It is the connection between them: whether one side lands harder, stays longer, rolls differently, moves pressure through another path, or changes first as the session progresses.
Real runs reveal what a short test can miss
Running mechanics change with speed, step rate, terrain, incline, footwear, and the demands of the session. Repeated wearable measurements make those changes visible in the environment where they actually happen.1,3
That creates a personal feedback loop: see the pattern, test a cue or shoe, run again, and learn whether the change held across real steps. Gait analysis stops being a one-time verdict and becomes part of training.
