I am a recreational runner (about 15 miles a week) and I live in an area that gets 360 sunny days a year so excellent eye protection is an absolute must.

I bought these because my regular shades tend to fog up before I hit the one mile mark. I didn't realize how heavy my regular shades were until I got these.

They are very light and only fog up when I wear them too close to my face. A minor adjustment allows the air to flow and the fog clears right up. I have worn them for 2 weeks and approximately 25 road running miles. I got the silver/orange style and they make me look like a 70s Comic Book heroine (that's a good thing). My small children think I'm a super hero. They call me Rainbow Girl. I'm not sure what her powers are, but I'll take it.

They seem durable. The price was about right. The shipping fees and timing were reasonable. I didn't experience my eyeball reflecting back at me that the other reviewer did and I like that others can't see my eyes with this model. Dunno why exactly but I like that bit of privacy.

The reasons I didn't give them 5 stars are because the arms interfere with my headset and that is very annoying. I have to adjust every half mile if I want to keep my music in my ears and their "footprint" is rather large. They take up a lot of real estate in my purse.

Otherwise a fine product and I would recommend them if you need something and don't want to spend a lot of money.
