RunScribe's comprehensive metrics highlight tradeoffs between the core elements of a runner's stride: Symmetry, Motion, Efficiency & Shock.


Efficiency metrics are correlated to running economy - an indicator of your running performance and potential.

Efficiency indicators are used to:
  • Establish a runner’s optimal pace
  • Evaluate training effect
  • Identify weakness based on efficiency breakdown
  • Assess the impact of footwear

Stride Rate
Flight Ratio
Contact Time


Shock is an indicator of stress on the skeletal system, and are measured at each footstrike. RunScribe provides Shock metrics for every footstrike and for the entire run.

Shock values are used to:
  • Identify injury risk
  • Evaluate training load
  • Assess shoewear

Motion metrics characterize running form, which can vary based on speed, terrain, footwear and fatigue.

Motion metrics are used to:
  • Assess form and variance while running in natural environments
  • Identify injury risk
  • Track recovery from injury
  • Improve footwear selection
  • Quantify the effect of gait retraining

Simultaneous left and right run data identifies imbalances. While some degree of asymmetry is normal, extreme asymmetry can be an indicator of injury risk.

Symmetry is used to:
  • Identify areas of dominance or weakness
  • Quantify the impact of physical therapy, orthotics, shoewear, strength & conditioning programs
  • Track progress in injury recover

Motion Profile

"Not many devices allow for practical change based on data, but I believe RunScribe gives us the tool to translate some of these nice metrics into practical change that influences performance."

Steve Magness - Science of Running

"As an elite running coach, every detail matters. I am constantly striving to minimize the occurrences of injury and enhance the effectiveness of our training. RunScribe is a tool that helps me accomplish this. It allows me to drill into the details and provides me with clear, actionable data."

Ryan Ponsonby - Elite Running Coach

"At our clinic we're fortunate enough to work with endurance, elite and Olympic runners for injury management and prevention. RunScribe is a quick and efficient way for us to confirm what we see in video analysis and the physical exam, quickly identify imbalances, show patients where their issues lie and quantify changes from therapy and orthotics. RunScribe has been extremely useful!"

Ian Chapple PT, Cert DN - Endurance Rehab

"Now Scribe Labs wearable technology can potentially prevent running injuries by analyzing your running form and running shoes."

Nick Pang - Natural Running Center
