Query: great running shorts

I'm a runner and I originally ordered one pair of these shorts because I wanted to find something to prevent the rub burn on my legs that i was getting on 3+ mile runs.I used them for about three weeks and was so pleased with their performance that I immediately ordered two more pair!!!Very comfortable, very breathable, and good wicking. They definitely keep me dry, cool and comfortable.I even received free shipping, but I'm not sure if that goes for all size/color combos.This item was a great investment.
