Started off well. I thought they felt good and fit nicely but as other reviewers stated one leg kept rolling down after walking for a while. I was on vaction and walked all day in 85 degree weather and the bands did not perform as I had hoped.  I ended up with painful chafing and spend most of the day fighting with the one band and trying to keep it from rolling down my leg.  If I wear them again it will only be for short periods of time.
