One of the most frequent questions among runners concerns the lifespan of a running shoe.
The short answer: most running shoes last between 600 and 800 kilometers (375-500 miles).
However, several factors can influence this duration.
Key Factors
Your Weight
A heavier runner will place more pressure on the foams.
Shoe Type
Performance-oriented models often use lighter foams that can lose their properties more quickly.
Surfaces Used
Asphalt generally wears out soles more than trails.
Your Running Technique
Certain areas of the shoe may wear out faster depending on your stride.
Signs It's Time to Replace Your Shoes
Pain Appears
If you start to experience:
- Knee pain
- Hip pain
- Foot pain
your shoes could be the cause.
Cushioning Seems Gone
You feel ground impacts more intensely.
Sole is Heavily Worn
Some areas show significant or asymmetrical wear.
Shoe Feels Less Stable
Foam can compress over time.
Can You Exceed 800 Kilometers?
Yes.
Some shoes can easily exceed 1,000 kilometers (620 miles).
However, their performance will generally no longer be optimal.
Should You Replace Your Shoes Even if They Still Look Good?
Absolutely.
The foam often degrades long before the exterior of the shoe shows obvious signs of wear.
Our Recommendations
For most runners:
- Monitor your kilometers/miles
- Replace your shoes between 600 and 800 km (375-500 miles)
- Don't wait for significant pain to appear
Preventive replacement is generally less expensive than an injury.
