These are such a genius invention.  All my other running sunglasses are over the top sporty looking and I wouldnt wear them for everyday.  Not to mention they're expensive and you cry if you lose them or your kids break them.

These simple shades work great for runners. I took them out for a 10 mile run with no slipping, no bounce, no issues at all.  They come in tons of cute colors, and Id actually wear them to the pool or park because they look stylish enough to be a normal pair of sunglasses, unlike other sport shades that look like you're going out for the Tour De France.

As for the fit, I was very pleasantly surprised.  I am a woman with a narrow face.  I can wear childrens glasses in some situations.  Unisex shades are usually a joke on me, creating a total bug effect.  I couldn't believe these fit me perfectly.  I love them and am buying a second color.
