TalariaTreadTracker
Your shoes know more than their mileage.
An 8-factor wear model that tracks how your shoes actually degrade — not just how far you've gone. Built on HealthKit, backed by research, private by design.
The "500 Miles" Problem
Most apps and even shoe manufacturers tell you to retire shoes after a fixed mileage. But a 5-mile trail run in the rain doesn't wear shoes the same as 5 miles on a treadmill. Distance alone isn't enough.
Terrain-Aware Tracking
Automatically detects trail, road, and treadmill via GPS elevation analysis. Trail runs carry a higher wear multiplier because uneven surfaces stress foam differently than flat pavement.
Biomechanics from Your Watch
If your Apple Watch records cadence, ground contact time, or vertical oscillation, those metrics feed into per-workout wear estimates using pace-aware targets.
Shoe Rotation Rewards
Research shows rotating shoes reduces injury risk by 39%. We credit your shoes for rest days — because polymer foam recovers measurably after 48+ hours off your feet.
Session Grouping
Warm-up walk, interval run, cool-down walk? We detect the full chain automatically and assign it to one shoe — capturing your actual workout, not three separate fragments.
8 Factors, One Wear Score
Every workout gets an "effective mileage" that reflects actual shoe stress. Here's what goes into it.
Terrain
Trail 1.3x, road 1.0x, treadmill 0.85x — auto-detected via GPS.
Elevation
Climbing adds equivalent mileage. GPS-smoothed to filter noise.
Pace
Faster pace = more impact force. Continuous interpolation, no step functions.
Temperature
EVA foam softens in heat and stiffens in cold. Both accelerate degradation.
Duration Fatigue
Longer runs change your gait. Runs over 60 minutes carry a fatigue multiplier.
Biomechanics
Cadence, ground contact time, vertical oscillation — all pace-normalized.
Rotation & Rest
Alternating shoes lets foam recover. Up to 35% wear reduction credited.
Foam Aging
Midsole foam degrades over time even unworn. +4% per 6 months on the shelf.
Why not just use Strava?
Strava counts miles. We count impact. They're complementary — use both. Strava tracks your fitness, TalariaTreadTracker tracks your shoe health.
