If there is a $50 pair of shorts that is comfortable, I haven't found them. You get what you pay for.

I now use the best Pearl Izumi and Assos shorts. I have at least 8000 miles on both of these shorts and they ride like new. The Assos are built better and will last longer but I actually find the PI's to be more comfortable. I might try some Hincampie's next.

Don't skimp on shorts. The difference between the cheap ones and the best isn't that much.
