Are your shoes worn out?


How to tell if your shoes are worn out…dead shoe walking

A commonly asked question is “how do you know when your shoes are worn out?” With improved production methods, the outsole (the part that makes contact with the ground) of the shoe often shoes very little sign of wear even after hundreds of kilometres. Conversely, if you have wide feet, or toes that poke up while running, you may prematurely wear a hole in the upper but still have a shoe that is otherwise perfectly function. For most shoes, the main area of concern is the midsole of the shoe where the cushioning is.  There are a few signs to be aware of including leg fatigue, increased impact noise, and loss of recoil in the ‘dead shoe test’.

As a general rule of thumb, expect to receive approximately 500-800km of life from your running shoes (that is 3-4 months of running 40km per week). Obviously lifespan can some can obtain a greater life with some only able to obtain 300-400km until the shoe is worn out. A variety of factors affect this, including runner weight, terrain, running gait, frequency of running (you obtain a greater lifespan by alternating two or more pairs of shoes) as well as other factors that are runner dependent.


Key signs you need to replace your shoes
