Probably that is the most frequent question of running athletes or marathoners. Running in old or torn shoes is one of the main causes of injuries. Generally, running shoes with torn and worn padding are less shock proof, and less durability. Using worn out running shoes continuously increases the stress and shock on your feet and legs that can be a cause of joint injuries. The easiest measure you can do to prevent future injuries is to purchase a new pair of running shoes as soon as your old pair are worn out.
But how can you determine if your old pair needs replacing? Never use the treads of your running shoes to determine if you must replace your running shoes. The part of the shoe called the midsole that provides padding and durability, normally tears down before the bottom shows major signs of tear. If you’ve been feeling muscle sprains or any kind of pain in your muscles and joints, particularly in your knees, you may be wearing running shoes that are no longer durable. Also, if a part of your running shoes are damaged, then it needs replacing.
The rule of thumb is to keep your running shoes for at least 500 miles of running intensity, based on your running routine, body mass and the surface ground where you run. People who have less body mass can get new running shoes, after exhausting the maximum running miles while heavier people should at least reach the minimum of 300 miles. If you run through on pebbled roads, you need to replace your running shoes than if you run on smoother surface grounds.
To be accurate, mark your calendar on the date you started your new running shoes so you will remember when to get a new one. If you are using a training routine with a running log, you should also record the date when you started using your running shoes to help you to keep track how many miles you’ve used them. Recording the start date on the interior padding of the shoes such as the tongue is also a great way to help your remember when you first started your new running shoes.
On the average lifespan of your running shoes, you can also buy another pair to alternate your runs. Your running shoes will last longer when you allow them to “breathe” and relax between your running routines. As well, getting a new pair of running shoes as an alternate will help you to get the idea when your old running shoes are ready to be discarded.
Even though you need a new pair of running shoes for every 500 miles worth of running, there are also ways to get to the optimum end of this running range. You can read on precautionary measures available on guides accompanying your purchase. Some store clerks are well-trained to help you with the idea of making your shoes last longer. Some running habits make the shoes more vulnerable to wear and tear. Generally, if you would always use your running shoes, do not expect higher durability and longer life expectancy.
If your old shoes are already worn out, but they are still okay, do not throw them away. You can give them to donation boxes for charitable institutions.
