The runner's modern tech stack.

Don't rely on memory or spreadsheets. Rely on automated data, AI, physical wear insights, and community benchmarks.

Passive Sync

Connect once and forget it. We passively monitor your Strava and Apple Health workouts in the background — every run automatically updates your shoe mileage. No manual entry, ever.

Injury Prevention

Degraded midsole foam dramatically increases impact forces and injury risk. We alert you exactly when shock absorption is compromised, backed by ACWR injury-risk analytics and weekly mileage trends.

Complete Run History

Every run is logged with pace, distance, and the shoe you wore. Smart auto-assign rules can even tag runs by pace, time, or day. Search and filter in seconds.

Shoe Deals

When it's time to replace, we scan 19 retailers and can send price-drop alerts for your exact model — right inside the app.

Smart Price Finder

Instantly compare prices across top retailers when your shoe hits its limit.

Smarter than a mileage tracker.

AI and rotation intelligence help you train better and extend the life of your shoes.
