How long does a pair of running shorts last most guys on here? I tend to wear out the crotch- specifically, the place where the seams meet- in my running shorts really quickly. After only about 18 months, I end up with holes in my running shorts. This doesn't bother me too much as I'm primarily wearing the shorts because of the liner and, realistically, I'm not ending up spread eagle too many occasions, but it still seems like these things should be lasting longer than a year and a half. I average between 50 and 80 miles per week throughout the year and don't take too much downtime, but it's hard for me to believe that that has much of an impact on how long I should be able to wear a pair of running shorts before getting a massive hole underneath my respectable but not outrageously sized johnson. Any help here?
