So, I was having some calf pain after running W4 of C25K, dispite stretching. Once I started walking again, it would gradually decrease tho. I was doing some research and it said an easy way to tell if you are a pronator is that the inside of the sole on the balls of your shoes will be worn down. I just started running really, and looking at old shoes that I wore for about 2 years on a day to day basis, I see that the middle of the ball of my foot is worn down, but the back outside of the heel is REALLY worn down. Does that mean anything? Should I be refit for shoes?
Looking at the inside of the shoe is probably a better indicator of what part of your foot strikes the ground first when you run. So if the heel of yours is worn out, you most likely strike the ground with your heel first.
Another neat test you can do is if you set your shoes on a table or something, look at them from the back and see which way they lean. If they lean in towards each other, that's the way you pronate. I can't remember which is which at the moment so I'm not going to say one or the other
