You should generally replace your New Balance running shoes based on the mileage you've accumulated or signs of wear, typically between 300 and 500 miles.
It's widely accepted that road running shoes, including models made by New Balance, have a standard lifespan somewhere between 300 - 500 miles, or around 500 - 800km. Lighter weight or minimalist running shoes might have a slightly shorter lifespan, usually somewhere between 250 - 300 miles.
The exact timing for replacement depends heavily on how much you use them. For example, if you're running 20 miles per week, you'll probably need to replace your running shoes after around 4 - 6 months of wear, based on the typical lifespan range. Higher mileage means you'll need to replace them sooner.
Here's a general guideline based on your weekly mileage:
| Weekly Mileage | Estimated Replacement Time |
|---|---|
| 10 miles | 8-12 months |
| 20 miles | 4-6 months |
| 30 miles | 3-4 months |
| 40 miles | 2-3 months |
Note: This is an estimation based on the 300-500 mile lifespan range.
Beyond just mileage, pay attention to the physical condition of your shoes. Signs that it might be time to replace your New Balance shoes include:
- Worn Out Tread: If the outsole is significantly worn down, especially in key areas like the heel or forefoot.
- Reduced Cushioning: The midsole feels flat, less responsive, or doesn't provide the same bounce or protection it once did.
- Visible Damage: Tears in the upper, cracks in the midsole foam, or excessive creasing.
- Uneven Wear: If the shoe wears down significantly on one side more than the other, which could indicate changes in your gait or that the shoe's structure is breaking down.
- New Aches or Pains: Experiencing new joint pain, muscle soreness, or developing blisters in areas where you didn't before can be a sign that your shoes are no longer providing adequate support.
Replacing your shoes when they reach the end of their useful life helps prevent injuries and ensures you continue to receive the comfort and support needed for your runs or activities.
