Ah! The feeling of putting on a new pair of running shoes! It truly is like stepping on a cloud. That is when you realize that the shoes you were wearing are really worn out. How do you know when you need new shoes? It’s simple. Shoes unfortunately don’t last more than 3 or 4 months. The cushioning is what wears out first. So, when you buy your next pair of running shoes flip your calendar forward 3 months and set a reminder that it is time to purchase new shoes.
