I do HIIT twice a week...and
brisk walking on other days...
sometimes my shins and thighs KILL me when im done.
Some say its my
running shoes(had em for 2 years), some say im overtraining and some say it could me my technique like not landing on my heels or etc.
I just wanted to know , as a general thought....how often should one change his shoes? I HAVE changed my souls inside of my running shoes with new ones and added a GEL sole to make it more comfy...it helped a bit but just some advice.
thanks
