To add to my last question , I inadvertantly put on my wives womens size medium. They seemed to have a bit more suport. I have worn these in the past but moved away over the summer months ( I sweat something bad). I started to wear them again due to a "runners knee" issue and will atest to these working miracles. After three days of not being able to run or even walk downhill I took these for a 3 mile trail run with not a twinge of pain.
