Before you buy a running shoe make sure you know the shape of your feet. Many running injuries suffered by runners are caused by wearing the wrong running shoes.
Shoe manufacturers design running shoes to fit different types of feet.
The most common feet shapes are
Feet Shape one
Feet Shape Two
Feet Shape three
Feet Shape Four
To know the shape of your feet step on a piece of paper and then trace round your feet using a pencil.
Next time you go to buy your running shoe remember to tell your running shoe seller the shape of your feet so that he can recommend the right running shoe.
