If you have to choose a running shoe for yourself, then you will have to first understand your feet type. There is a simple test to verify what your feet type is. Wet your feet and place it down on a paper.
If the impression captures almost all of your sole, then you have a flat foot. This means that while walking or running, your feet fall on the outer side and then roll inwards, and then take the ground support to move you forward. A flat footed person needs a stability shoe.
If the foot impression misses some part of the middle portion of the sole on the inner side, then you have neutral foot and your shoe type will be neutral. If the foot print misses most of the middle portion of the sole, then you need shoes that can absorb shock, because your legs do not roll onto the sole completely to move forward.
Shoes can be divided into three categories, broadly speaking. They are: Stability running shoes, Motion Control Running shoes and Cushioned running shoes basis the foot type. Once you have established your foot type is when you can go on to purchase the shoe that fits you the best.
Once you spot the pair of shoes which has the right cushioning system– in case you have the light foot print- then you must first try it on. The cushioned running shoes should be worn and then a trial run be done to test your level of comfort. If the shoes are comfortable enough while jogging and walking, that is only when you should purchase them.
In case you have a flat foot and you need a stability shoe, ensure that the size is right. Wear it and stand and feel whether the pressure has been evenly distributed or not. If not, try another one. If you have worn a shoe and you are able to feel or see the toe getting pressurized against the insides of the shoe, then you should not purchase it.
It is important that you choose the right shoe for your feet, because if the shoe does not fit right, it may even cause leg injury.
