Who would have known? One size does not fit all!! I am on the smaller side for a female, but still, why is it so difficult to find women specific sunglasses for sports that aren't ridiculously expensive? They looked huge on my face, they never slipped since they instead bounced around the instant I started running, the nose piece was too wide to sit snug. What a shame! I wanted to love these, they have great colors and were very light feeling, but alas! One size does not fit all!
