Choosing the right running shoe is just as important as choosing the right nutrition or workout plan. Because everyone is different not one shoe is right for everyone. The best idea is to go into a running store and ask them what shoe fits your particular foot. You don’t want to be someone with a wide foot trying to wear narrow shoes. Also there are many types of shoes for different terrain. As for how long till you replace them. Typically shoes last around 6 months before they start losing their stability and tread. If you are a very active runner you might be replacing them right at 6 months or maybe even before. If you are a casual runner and don’t put in a lot of miles during the week you may be able to extend it out past 6 months.

The best running shoe will vary from person to person. Everyone has different running mechanics and heel to toe patterns so not everyone can wear the same shoe. I suggest you go into a running store and have them check out your walking stride. They are able to see where and how much pressure you put on your foot and whether you need a shoe meant for comfort, stability or a lightweight one. Some research has shown that you should change your running shoes anywhere between 300-500 miles ran or about every 6-7 months. You can also check and make sure you have traction on your sole and how your feet feel after use to determine when to get new shoes.

It is important to invest in good running shoes to ensure you get the support that you need while running. The first thing you need to do is identify your walking pattern to determine what shoes work best. Making sure that your shoe is a good fit for running can save you unwanted joint pain up and down the kinetic chain. I always encourage clients to go to a running store to get help finding the perfect pair. As soon as you start to feel the support deteriorating it's time to get a new pair.
Before selecting a running shoe you should consider the type of terrain you most commonly run on, ie.. road running, trail running or cross training shoes. I recommend going to a running store to determine your typical walking pattern for example if you have a neutral, pronated or supinated(foot) because this will help you select the most supportive or correctional shoe for you. The foot tends to swell throughout the day so you would get a more accurate fitting towards the end of the day, in addition you should check to see if the width of your index finger fits between your big toe and the top of the shoe. Make sure the shoe is wide enough to fit the width at the ball of our foot. Generally shoes should hold their support and cushion for 3-6 months or after 350-500 miles of use.
