I never really used special socks when exercising before.  After starting to increase my running mileage from 6 to 9 miles per run, I started getting more blisters from sweat.  These socks solved all of that.  They will keep your feet dry and cool.  After a run, take off your shoes and your feet will be dry in minutes.  I wish they made taller versions in black and brown so I could wear these with my work shoes!
