Pronation is a condition which has to do with the rolling motion that takes in the effect of landing – when you run – on the outside of your heel as your heel strikes the ground. It is very crucial for you to understand how you walk and your pronation as these factors will go a long way in helping you decide on the particular type of running shoes you should purchase. Many running shoes out there can alter or improve your pronation significantly; therefore, take some time to carry out a little research about your potential choices as well as how they impact the way you walk.
