When used for its intended purpose, Brooks footwear has an expected lifespan of 500-800 km / 300-500 miles.

If you used your trainers for daily wear, standing in them would be equal to walking up to 4 km/h, the average person’s walking speed. Standing in your shoes could be reduced to less than 3 km/h, and for 8 hours would be a daily approx. of 15-25 km of impact to the support and cushioning components of your shoes. In a month, you’d average about 350 km of wear. When used for daily wear, they will actually degrade more quickly than when worn specifically for running due to constant pressure on the mesh and cushioning components.

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.
