My new running shoes arrived. Being a life long runner nerd, I like to study where the tread got thin on my old ones. All in the toes and mid-foot. You can tell a lot by looking at the bottom of old shoes. If the tread is worn off on the 'inside' or 'outside' or back... it can tell you about your foot strike.
