When used for its intended purpose, Brooks footwear has an expected lifespan of 500-800 km / 300-500 miles or 6-12 months of regular use.
The lifespan can vary based on a runner’s stride and technique as well as weather, running surface and temperature. Each individual, while running in the same conditions will experience different wear based on weight, impact and gait.
Running shoes are designed and manufactured for forward linear movement, so other uses (for example, other sports which may require lots of lateral movement) may result in wear that is unexpected.
