Love the look, design, and style. I'm picky and made sure to try them on and wear them in the optometrist's office for a good 15 minutes and they felt fine. Got them in and they felt fine. After the first day they were very loose. The arms irritated my ears, and the slick plastic that's on the nose is very slippery and slides down. Went back and compared to the pair at the store, and the arms on mine spread out more. They warmed em up to adjust them inward and they fit nice and snug, didn't hurt, and didn't move. But after a day they were loose again. Even the smallest frame size is huge and I have a very normal head. The ones in all the stores make it feel great but in a short time they loosen up, the arms spread out, and it's like wearing clothes 4 sizes too big- they are uncomfortable become annoying. Looking at some of the Nike now as replacements. Would not recommend and would most likely not purchase an Oakley prescription eyeglasses frame.
