I wear these glasses everywhere.  I love them.  I am a cycler and runner, and they look and fit great.  They are durable as well and I have worn mine every day since I bought them in the spring.  I actually just bought a second pair in a different color.  They are vented so they don't fog up and are lightweight and comfortable and do not slip off of my face.  I use a bluetooth headset and have no problem because of the design of these glasses wearing both of them at the same time.  I cycle about 120 miles a week and they are outstanding for keeping the sun and bugs out of my eyes!
