When do i replace my running shoes?
Ok, this really isnt a simple question. Things that need to be considered are: your wait, the distance you run on average, type of shoe you have. If I remember correctly, most road shoes last about 400miles. Another note: if you dont replace them often you could develope serious problems like shin splints
Reply:Well every 350 - 400 miles, or every 6 mos.
