Here are some suggestions:
— Don’t wait to buy your next pair of shoes until after your current trainers are completely dead. If you offset your purchases and hold on to your existing shoes longer, you can start to rotate two (or three) pairs of shoes.
— Avoid running your shoes into the ground by wearing them to mow the lawn or for non-running activities. You’ll be able to extend the life of your shoes and revert to your old favorites in the back of your closet while they still have life in them.
— If you do plan to buy two pairs at the same time, ask your local running shop for a slight discount on the second pair. (You can also look for sales, either closeouts at running stores or online stores, but my advice is to only buy discounted models if you already know how they fit and perform on your feet.)
— Make an effort to vary the surfaces you run on during any given week and wear appropriate shoes. Mix things up by running on paved roads, gravel roads, dirt paths, rocky trails, concrete bike paths or a track.
— Be sure you don’t run in a single pair of running shoes too long. If a shoe is completely worn out, it could increase your odds of developing overuse injuries.
