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

& Clinicians
Hear from runners and clinicians who've transformed how they train and recover with Aletheia.
"It's almost like having an assistant coach with me — helping me stay aware of how I'm moving, when I'm compensating for an injury, and when I need to slow down."
Cavin Parrilla
Injury Prevention"What Aletheia has done for me is connect how I feel during a run with what's actually happening biomechanically. It has given me confidence and comfort in my running again."
Jeff Neal
Started Running at 54"Right away, I could clearly see that my left side wasn't producing as much force as my right side. It's helped me realize how much more I'm capable of than I originally believed."
Kaitlin Carew
Sub-3hr Marathon Goal"I learned that I'm actually a much higher-impact runner than I thought. The biggest benefit has simply been the knowledge and awareness the data provides."
Laura Pett
Chicago Marathon"Aletheia gives runners access to biomechanical feedback every single run in a much more practical and preventative way than expensive lab testing."

Victory Performance & Physical Therapy
Physical Therapy Clinic · Los Angeles, CA
"When we integrated the run sensor into our Running Assessments, we immediately noticed how closely the data aligned with what our physical therapists were already observing. That validation matters — it reinforces our clinical findings and gives us something tangible to share with our clients so they can see exactly what we see."
"Proof of concept isn't just a nice-to-have — it's a game changer for client buy-in and motivation."
Performx Physical Therapy
Outpatient PT Clinic · Salem, OR
"As an outpatient PT clinic, we use this app to guide our running assessments, and it's become a genuine asset to our practice. The insights are detailed enough to inform our clinical decisions without slowing us down, helping us build smarter, more individualized plans."
"A great tool backed by a great team."
