These work great for me.  Not to dark that I can't see in the shade.  I feel like they protect my eyes form harmful rays, not to mention the skin around my eyes (I am not getting any younger).  There are not my style to run other than for exercise.  Good fit for me, I am 5'6" and 125 lbs.  They don't slip off, they do not fog.  I do drip sweat on them and have to clean them but I don't expect anything less.

Great glasses and would buy again.
