I love my Smith Method glasses! They are sporty yet girly. A little round, but not pop star round. They don't slip--I wear them running and biking. They are EXACTLY what I was looking for. They are a little tight (another review had mentioned this) but I'm used to them now, and they don't bother me. In fact, I wore them on a two hour bike ride the other day and didn't even notice they were on. I love 'em!
