The average life of running shoes according to research by New Balance is estimated at around 480 to 800km (300-500 miles) depending on your weight, running mechanics and environment. For example, a 100kg runner who overpronates will get less wear out of their shoes than a 54kg person who has improved form and stride.

How long will my trainers last when training for a marathon?
Most marathon training plans can range between 400 and 700km depending on ability and experience. In this instance, a runner would need to consider purchasing a second pair of running trainers for the latter stages of training or a trainer rotation plan that allows you to spread the miles out over a couple of use case pairs.
How can I easily track my running shoe mileage?
You can easily add your pair of shoes to most running apps so you can effectively monitor how much mileage your trainers have covered, so when they hit the 480-800km mark you can keep an eye out for any imperfections that might hinder your run.
