If you want to build a stronger running foundation you should rotate your shoes.
I’d like to begin with a Disclaimer: I’m not a Podiatrist, nor a Physical Therapist not even a Foot Magician. Everything I’m describing in this post is from my own personal experience as well as knowledge I have gained from running experts.
Running increases the muscular endurance of our feet, legs and even the hips. Using the same shoes on every run will work on the same group of muscles all the time. If you used one or even two pairs in rotation on different days you could benefit.
A Shoe for each run.
Personally, I rotate between three sometimes even four pairs in a week. I run my Long Runs with a cushioned 10mm drop (heel to toe offset). A flatter 4mm drop and less cushioned for faster runs. A zero drop less cushioned for medium long runs and easy runs. And from time to time a barefoot shoe for easy short runs and recovery.
By mixing up the shoes gives my legs and feet a more complete workout. It truly builds your lower legs much stronger. Something that I can definitely notice. Although the cushioned shoes are comfy, the more minimal zero drop do more good to your muscles. They stretch the fascia muscles and makes them more flexible. Also the Achilles and Soleus and many more muscles will benefit.
Rotate what you already have
Don’t go out and buy three different pair of shoes all at the once. Rotate what you have in your closet first. Take out maybe an older shoe that has some life still left on its sole. If you already have a shoe that has more than 100 miles on it now is the time to shop for a new pair. Talk to your local running store experts. Ask them for a different drop shoe than the one you already own. Make sure the shoe is the right one for your feet (Pronation). Once this pair reaches the 100 mile mark is time to shop for a new one. Throw that in the rotation, Soon you will have choices to make on your runs. Remember since you are rotating your shoes they will last you for a longer time till they reach their end.
Choose the right shoe carefully
Although I own a few pair of shoes from many different brands they are all the same in one way. When it comes to Pronation Control they all fall in the Neutral category. They may vary in drop, cushion and style, but they are all Neutral. You should know your Pronation Control category and always stick with it. If you decide to buy a pair with a different drop than you are used to make the change slowly. Allow for transition time. The bigger the difference in drop the longer the transition. Remember you will be stressing tissue that has not been stressed and you will be risking injury.
I believe shoe rotation is a great way to build an injury free running body!
