It isn’t very often that I put on a new pair of running shoes. I started my last pair of shoes on 30 September 2010. Between then and May 2013 I ran approximately 1075.5 km, or 668.28 miles, or roughly 25.5 marathons. Over 32 months that really isn’t all that much, I suppose. But it felt, at times, like a fair bit to me.
According to a number of sites on the Internet, I should have changed shoes after about 400 miles. I’ll have to keep an eye on that. Perhaps a two-year maximum ought to be my goal.
