How It Works 🧠
Our Shoe Life Calculator considers several factors:
- 🌍 Terrain Type: Different surfaces impact shoe wear differently. For example, trails are harder on shoes than roads.
- 📏 Weekly Mileage: Higher mileage can actually extend shoe life slightly due to more consistent use.
- ⏳ Base Life: We start with an average shoe life of 400 miles, then adjust based on the factors above.
The Calculation Process:
- Start with the base life of 400 miles.
- Adjust for terrain:
- Road: +10% (easier on shoes)
- Trail: -20% (harder on shoes)
- Track: +20% (consistent, soft surface)
- Treadmill: +30% (very consistent surface)
- Adjust for weekly mileage:
- High mileage (>40 miles/week): +20% (more consistent use)
- Low mileage (<15 miles/week): -10% (shoes may deteriorate from disuse)
- Calculate weeks until replacement by dividing the adjusted shoe life by weekly mileage.
Remember: This is an estimate. Always check your shoes regularly for signs of wear and replace them if you notice reduced comfort or support, regardless of mileage. Happy running! 🏃♂️💨
