What do the bottom of your running shoes look like?
Mine look like this - The shoe on the left was the one I wore for the marathon and the shoe on the right was from all my marathon training. As you can see, I wear out the toes pretty good. The rest of the shoes has pretty average wear on it.
I was planning on wearing the left shoe throughout my next half marathon, but since the toe is already showing wear I decided to use one of the 2 new pairs in my closet (maybe this will also help with my motivation :))! I guess that means I need to look for more at the next expo!
