I've been wearing Smiths since around 98 and have owned the Slider 01, Spoiler, Approach, Directors, Backdrop, and now these Challis. I've like them all. These are now my favorite. I was a little nervous because their were no reviews and their was no local store that had them to try on. I took a chance and glad I did. I really wanted Chromapop lens, and went to a few local stores to see which chromapop lens I liked. I was having a tough time deciding between these and the Dolen or the Dover. I have a medium face and these fit perfect. I got the flat black frames and opted for the gray green lens. So far I love them. If I get extra cash, I might buy the flat black Dover with the blue mirror Chromapop lens next. I run, cycle, paddle board among other things and also wear them at work.
