When you’re putting in high volume run weeks you could help prevent injury by having more than one pair of running shoes.  Alternate each pair of shoes from one run to the next.  This helps your small connective tissues and joints get a very slight break by working in a slightly different way.  The change will be small, but this is often enough to keep minor problems from flaring into bigger injuries.  Having two pairs of shoes also serves you well when you’ve been forced to run in wet weather.  Save one pair for wet runs, the other for dry.  It’s also been shown to extend the mileage you’ll get out of each pair of shoes.  The break your shoes get helps the rubber recover before your next outing.  I can’t say for sure if that last point is on the mark…but you never know.
