My wife has a tough time finding cycling glasses that fit properly...she needs some that run on the small side, and even though she's tried several pair that were supposedly made for smaller features, she has yet to find a pair that works for her. We've wondered if there might be a manufacturer out there who makes a pair of glasses with adjustable temples of some sort. Does anyone out there know of a product like that?

Rudy Project are pretty asjustable--both nose and temples can be bent to fit you better. They also offer some frames for smaller faces. Worth looking into. Good luck!

The Performance Siren model is for narrow faces. They fit my wife's face perfectly and she has a very slender face. Nothing else came close. Plus, they're mid $20s on sale, come with 3 different lenses and well, they work. She loves them.

This guarantees that they fit any face shape.

You can find it here .

I don't have an experience with this particular model. I have another one called Genesis. Fitlogic just came out a couple of months ago. She should try if nothing else works.

And here is the home page showing a demo how they fit on different faces.
