Track What Really Matters
The Aletheia sensor offers comprehensive analysis of various metrics to provide a complete picture of your running form and performance.
Efficiency
Optimize your energy expenditure per distance
Higher efficiency means less energy wasted per mile
Braking
Measure impact deceleration to reduce injury risk
Lower braking forces indicate smoother forward motion
Impact
Track landing forces to prevent overuse injuries
Balanced impact reduces stress on joints and tissues
Sway
Track side to side force expenditure
Less sway means more efficient forward propulsion
Variation
Track how forces change over time
Consistency in force patterns indicates stable form
Warmup
See how long it takes for you to warmup
Shorter warmup times show better readiness
Endurance
Measure how long you can last in a session with good form
Form degradation indicates fatigue and injury risk
Hip Stability
See how strong your hips are
Strong hips prevent collapse and maintain alignment
Hip Mobility
See how mobile your hips are
Good mobility allows for proper stride length
